I totally agree that you don't have to live on ramen and Hamburger Helper as a grad student...ugh.  I do eat ramen but only occasionally.  You can get inexpensive food options and cook them.

One of the things I decided as a grad student was that the stipend they paid me was not enough to live the way I wanted, so I got an addition part-time job.  I've been doing something on top of grad school since my third year when I finished coursework and had the time.  This has the added benefit of giving me non-academic skills to take into the non-academic workplace should I choose to go that route.  I've TA'ed courses for more money, worked an as intern for a market-research firm, worked as a hall director in the office of residential life, worked as a statistical consultant, and worked as a student tutoring assistant in the library.  If you live in or near a big city, there may be lots of part-time jobs that you can do for 10-15 hours a week to make a little extra cash on the side.  Some of them may be office work that will give you useful skills and experience to talk about should you choose to seach for a non-academic job.

The other half of this is to be frugal.

-Some people budget every dollar that leave the wallet.  I neither have time nor interest in doing this.  What I do is budget for essentials.  $X for rent, $X for utilities and phone, $X for food and $X for other essential bills that have to get paid every month.  I set those aside in a separate account.  The rest is mine to spend however I want.  So some months I may decide to spend, I don't know, $100 on coffee and $0 on movies, whereas other months I spend $150 on clothes and $30 on coffee.  But be cognizant of what you are spending and know where you need to cut back.

-Do free and cheap things.  I live in NYC.  I have yet to see a Broadway play, the NYC Ballet, the opera, etc. because they all cost lots of money.  I would like to do those things, but I'd rather eat good food.  So I choose to do things like go to the museums (all cheap or free with my university ID), go to the park, walk around, etc.  My city has free concerts all the time for no reason at all, lol, and sometimes the university has free or cheap events.  Search out student discounts.  And I'm friends with students and friends at a similar life stage, so I just remind them whatever we do needs to be cheap.

-Shop for clothes on sale and stop buying clothes when you don't need anymore.  Only buy more when you need to replace something.  Do invest in some quality, though - there's a balance between quality and price.

-Cook most nights.  Seriously, I have started saving so much money by cooking rather than eating out.  Learn to make meals that use a lot of the same ingredients.  When I lived alone, dinner Tuesday would become lunch Wednesday and sometimes also dinner Wednesday depending on how much came in the package.  I'm married now so we usually eat it all but it's still cheaper than eating out - and healthier and tastier, too.

-Housing.  I have met so many grad students who make a face at living with roommates, even one.  They claim that they are completely unable to live with other people, and they would rather pay $$$$ to live alone than $$ to live with a roommate.  I am not one of those.  I love people, and I don't mind sharing my living space - I actually prefer it.  And generally speaking, the cheapest way to satisfy housing needs is to acquire some roommate(s).  You can find respectable, quiet, private, sane people out there to live with - I've lived with several of them.  Other grad students need housing, too.  I once had a roommate who I saw for maybe like 15 minutes the entire week - she was always gone.  I've had other roommates who I'm still friends with to this day.  It can be really pleasant, I promise.

-Related to the above...I would personally investigate any neighborhoods.  People have different definitions of "dangerous" or "run down."  I lived in a very nice neighborhood in upper Manhattan that a lot of other students didn't want to live in because it wasn't trendy or filled with nice restaurants and shopping.  The trade off was that I got a relatively large apartment that I only had to share with one other person for a pretty low price.
 
Whether renting on the market is cheaper than living on campus really depends on the city and the university.  My university has two campuses.  The main campus is in a very trendy/expensive area, and renting through the university is cheaper than renting an apartment of comparable size and quality in the same neighborhood.  But if you are willing to commute just a little bit further (and I'm talking 30 minutes or less on the subway) you can pay a lot less, or get more for the same money.
 
The medical center campus is in a more residential/less expensive neighborhood.  I would say that the on-campus housing there is either the same price or actually more expensive than the other housing available in the area; not only that, but the market rental units were generally nicer and better maintained than the campus housing, with better amenities and probably more space.

I am assuming that you're in an American-style program, with ~2 years of coursework before comps and dissertation. I will say that I felt kind of similarly in my first two years of graduate school; the challenge was the volume of work I was being expected to do, not the type. I went to a small liberal arts college where close reading, deep discussion, and analytical writing were expected parts of the curriculum, so doing these things in graduate school was not a challenge. I definitely did grow and learned a lot of new material, but I didn't necessarily feel like I had to quickly ascend to a new level of understanding or anything like that. I did get the distinct feeling that some of my colleagues had different educational experiences and that there were areas in which the seniors at my undergraduate college may have excelled, also (particularly the writing and analysis).
I also don't think graduate school felt like getting into depth on a narrow topic until after my coursework. I didn't feel like I was delving really deeply until comps, honestly, and my dissertation was really the pinnacle of that.
A doctoral program is largely self-directed, especially after year 2 or so. So if you want to dive into things more intellectually, set yourself up for that. Take an independent study with the theorist in your department, or work on a collaborative project with them that might result in an article/monograph. Work on your own projects that are more theoretical and intellectually deep in nature. There are programs that will allow you to take a semester at another university to work on such a project. Or you can start a cross-university collaboration with a researcher in a related area. A lot of the intellectual fulfillment you'll get will be independent work. Developing a close working relationship with advisors is also self-directed.
I don't think choosing to do another PhD is a good idea necessarily. Remember that a doctoral program is also customizable and tailored, so if you want to take classes or work with someone in the philosophy or history department at your own university...arrange that.
Also, most programs will not admit you for a second PhD if you already have one, unless it's in a wildly different field.
 but being on a grad stipend for another 5 years certainly beats working outside academia.
Hoo boy, I would strongly disagree with that. But I think it depends on your values, wants, and needs. By the time I was nearing the end of my doctoral degree, I was real tired of living on a grad student stipend. But autonomy and theoretical analysis were not important to me (on the contrary; I much prefer applied work). If it is super important to you to do theoretical work, that may be different for you.
 

About your dog: I think that depends entirely on you and your program. I am in a social science program where the majority of my analysis and writing can be done from home, and I prefer to work from home or from a library (as opposed to my cube in the windowless cube farm). When I was taking classes I was generally there from 9-6 or so, but now that my coursework is finished I am rarely at the school itself. I go for meetings, seminars, interesting kinds of things and I do most of my work remotely. My time is verrry flexible, and if my building didn't prohibit it I would get a dog in a heartbeat. Another thing to keep in mind: a dog can be a great comfort when you're all stressed out over graduate school.

Advice?

Age:
-Don't feel like you have nothing to offer just because you are younger. I was 22 when I started graduate school. You got accepted to the program for a reason, and chances are you are just as equipped as any older students are to successfully complete the program, just in a different way.

-Your older classmates may be just as terrified as you. Talk to them. You have a lot in common. You are, after all, in the same place.

-You will feel like an imposter, like you don't belong, or like you are constantly behind. Or all three. It's normal. It will pass. (Well, sort of.) People of all ages go through this.

Adviser related:
-If you are lucky enough to get both research interest fit and personality fit perfect, congratulations! But sometimes, personality fit is more important than research interest fit as long as the research isn't too different. A great adviser is interested in your career development, likes you as a person, advocates for you, and wants to hear your ideas. Even if his or her research is quite different from yours, they may give you the autonomy to work on your own projects and just supervise you. A bad personality fit will drive you nuts, even if you love his or her research. Consider that when evaluating your adviser fit. (This will vary by field: research fit may be less important in the humanities, more important in the natural and physical sciences. Social sciences are somewhere in-between.)

-Don't be afraid to be straight up blunt with your adviser when it comes to asking about your progress. Ask if you are where you should be both academic program wise and getting-a-job-after-this-mess-wise.

-Be proactive. Advisers love when you draw up an agenda for your one-on-one meetings, come with talking points and progress to share, have concrete questions to ask, and have overall shown that you have been thoughtful and taken control of your own program. Of course, this won't immediately come easily to you, but in time you will work up to it. Every semester I type up my semester goals, and at the beginning of the year I type up annual goals. I show them to my adviser and we talk about whether they are too ambitious, or whether I need to revise them, and how I can meet them.

-Don't expect your adviser to actually know what courses you have to take to graduate. They will know about comprehensive exams and the dissertation, but a lot of professors don't really keep up with the course requirements, especially if their program is in flux. Get you a student handbook, and find out what you need to take. Map it out in a grid, and check off things when you finish them. Show this to your adviser every semester. You may have to explain how such and such class fills a requirement.

-Nobody loves you as much as you, except your mother. Keep this in mind as you take in advice from all sources, including your adviser. Your adviser is there to guide you, but that doesn't mean you have to do everything he says.

Studying:
-You will have to read more than you ever did before, in less time than you ever have before, and you will be expected to retain more than you ever have before. The way that you studied in undergrad may need some tweaking. Be prepared for this.

-Corollary: you may find that your methods change with age or interests or time. I preferred to study alone in college, but in grad school, I prefer to study in groups. It keeps me on task and the socialization keeps me motivated. You may find that you shift from being a more auditory learner to a visual learner or whatever.

-You will feel behind at first. This is normal.

-At some point you will realize that your professors don't actually expect you to read everything they assign you. This, of course, will vary by program, but there will be at least one class where the reading is actually impossible to do in one week. The point is to read enough that you know the major themes and can talk intelligently about them, and then pick some of the readings to really dig into and think more deeply about.

-For most programs, don't worry so much about grades. If you stay on top of your work and do what you're supposed to, you will probably get an A. How much grades matter varies from program to program. In some programs, a B is a signal that you are not up to par, and more than a few Bs will warrant a discussion with your adviser or the DGS. My program isn't like that - A, B, it's all meaningless. My adviser doesn't even know what my grades are. But at almost all programs, a C means you need to retake the course, and two Cs means you have to convince the DGS not to kick you out.

Extracurricular activity: What's that? No, seriously:
-A lot of your time will be unstructured. You will have coursework, but most grad classes meet once a week for two hours and you may have three classes. You may have meetings with your adviser every so often and some seminars or things to catch (like we have grand rounds and colloquia that are required), but a lot of time will be unstructured. However, since you have so much more work than you had in undergrad, you actually will have less free time than you had in undergrad. This may initially cause you great anxiety. It did for me. Some people love unstructured time, though. (I don't.)

-Because of this, you'll have to be planful about your non-grad school related stuff.

-TAKE TIME OFF. DO it. It's important for your mental health. However you do it doesn't matter. Some people work it like a 9-5 job. Some people take a day off per week (me) and maybe a few hours spread across the week. Some people work half days 7 days a week. However you do it, there needs to be a time when you say "f this, I'm going to the movies."

-Find your happy place, something that keeps you the you you were when you came in. I love working out. It gives me energy and I feel good. I stay healthy. I also love reading fiction, so sometimes I just curl up with a good book, work be damned. You have to give yourself permission to not think about work, at least for a couple of hours a week. You may also discover new hobbies! (I never worked out before I came to graduate school.)

-Your work will creep into all aspects of your life, if you let it. This is why I hate unstructured time. You will feel guilty for not doing something, because in graduate school, there is ALWAYS something you can do. ALWAYS. But since there will always be more work, there's no harm in putting it aside for tomorrow, as long as you don't have a deadline.

-You may need to reach outside of your cohort for a social life. None of my close friends are in my doctoral cohort. I've met master's students in my program, master's students in other programs, and I know a few non-graduate students I hang out with, too. Go to graduate student mixers. (If your university doesn't have any, organize some, if you like planning parties.) Join a student group that doesn't take up too much time. I had a doctoral acquaintance who kinda laughed at me because I joined some student groups other than the doctoral student one, and I was usually the only doctoral student in those groups, but I met some close friends (and future job contacts) and had a good time.

-DO NOT FEEL GUILTY FOR WANTING A LIFE OUTSIDE OF GRADUATE SCHOOL. This is paramount. This is important. You are a well-rounded, complex, multifaceted human being. NEVER feel bad for this. Everybody wants some kind of life outside of work. Yes, you may loooove your field, but that doesn't mean you want to do it all day long. Some other doctoral students, and perhaps professors, may make you feel bad about this. Don't let them. Just smile and nod. Then disappear when you need to.

Career:
-This is job preparation. Remember that from Day One. Always be looking for ways to enhance your skills. Read job ads and find out what's hot in your field, what's necessary, what's in demand. For example, in my field statistics and methods are a hot commodity, and they're not a passing fad. I happen to really like statistics and methods, so I have pursued that as a concentration of mine.

-Don't be afraid to take on volunteer work and part-time gigs that will give you skills that will be useful both inside academia and out, as long as it's not against your contract. Your adviser may be against it, but he doesn't have to know as long as it doesn't interfere with your work.

-If you want to work outside of academia - if you are even *considering* the possibility - please please definitely do the above. Even if you aren't considering it, consider the possibility that you won't get a tenure-track job out the box and that you may need to support yourself doing something else for a while. You will have to prove to employers that you have developed usable, useful skills and this is one of the easiest ways to do it. But don't overdo it - get the degree done.

-For more academic related ones - always look for opportunities to present and publish. Presentations look good on your CV. Publications look better. When you write seminar papers, wonder if you can publish them with some revision. Write your seminar papers on what you maybe think you may want to do your dissertation on. Even if you look at them three years later and think "these suck," you can at least glean some useful references and pieces from them. Discuss publication with your adviser early and often, and if you have the time and desire, seek out publication options with other professors and researchers. But if you commit to a project, COMMIT. You don't want to leave a bad impression.

-If you can afford it, occasionally go to conferences even if you aren't presenting. You can network, and you can hear some interesting talks, and you may think about new directions for your own research. You can also meet people who may tell you about jobs, money, opportunities, etc.

-Always try to get someone else to pay for conference travel before you come out of pocket. Including your adviser. Do not be shy about asking if he or she can pay. If he can't, he'll just say no. Usually the department has a travel fund for students, but often it's only if you are presenting.

-If you are interested in academia, you should get some teaching experience. There are two traditional ways to do this: TAing a course, and teaching as a sole instructor. If you can help it, I wouldn't recommend doing a sole instructor position until you are finished with coursework. Teaching takes a LOT of time to do right. You should definitely TA at least one course, and probably a few different ones. But don't overdo it, if you can help it, because again, it takes a LOT of time. More than you expect at the outset. If you are in the humanities, I think sole instructor positions are very important for nabbing jobs so when you are in the exam/ABD phase, you may want to try at least one. If your own university has none, look at adjuncting for nearby colleges, including community colleges. (I would wager that the majority of natural science/physical science students, and most social science students, have never sole taught a class before they get an assistant professor job. At least, it's not that common n my field, which straddles the social and natural sciences.)

-Always look for money. Money is awesome. If you can fund yourself you can do what you want, within reason. Your university will be thrilled, your adviser will be happy, and you can put it on your CV. It's win-win-win! Don't put yourself out of the running before anyone else has a chance to. Apply even if you think you won't get it or the odds are against you (they always are), as long as you are eligible. Apply often. Apply even if it's only $500. (That's conference travel!) Money begets money. The more awards you get, the more awards you will get. They will get bigger over time. If you are in the sciences and social sciences, you should get practice writing at least one grant. You don't have to write the whole thing, but at least get in on the process so that you can see how it's done. Grant-writing is very valuable both in and outside of graduate school.

-Revise your CV every so often. Then look and decide what you want to add to it. Then go get that thing, so you can add it.

-The career office at big universities is often not just for undergrads. I was surprised to learn that my career center offers help on CV organization and the academic job search, as well as alternative/non-academic career searches for doctoral students. In fact, there are two people whose sole purpose it is to help PhD students find nonacademic careers, and they both have PhDs. This will vary by university - some universities will have very little for grad students. Find out before you write the office off.

-It's never too early to go to seminars/workshops like "the academic job search inside and out", "creating the perfect CV," "getting the job," etc. NEVER. Often the leader will share tips that are more aimed towards early graduate students, or tidbits that are kind of too late for more advanced students to take care of. This will also help you keep a pulse on what's hot in your field. It'll help you know what lines you need to add to your CV. And they're interesting.

Other:

-Decide ahead of time what you are NOT willing to sacrifice on the altar of academia. Then stick to it.
I'm serious. If you decide that you do NOT want to sacrifice your relationship, don't. If it's your geographical mobility, don't. I mean, be realistic, and realize that there will always be trade-offs. But you have to think about what's important to you for your quality of life, and realize that there is always more to you than graduate school.

-If you don't want to be a professor, do not feel guilty about this. At all. Zero. However, you will have to do things differently than most doctoral students. Your adviser will probably never have worked outside of the academy (although this may vary depending on the field) so he may or may not be able to help you. But you have a special mission to seek out the kinds of experiences that will help you find a non-academic job. Test the waters with your adviser before you tell him this. My adviser was quite amenable to it, but that's because I told him that my goal was to still do research and policy work in my field just not at a university, AND because it's quite common in my field for doctoral students to do non-academic work. If you're in a field where it's not common (or where your professors refuse to believe it's common, or it's not supposed to be common)…well, you may be a little more on your own.

-Every so often, you will need to reflect on the reasons you came to graduate school. Sometimes, just sit and think quietly. Why are you doing this to yourself? Do you love your field? Do you need this degree to do what you want to do? Usually the answer is yes and yes, and usually you'll keep on trucking. But sometimes when the chips are down you will need to reevaluate why you put yourself through this in the first place.

-To my great dismay, depression is quite common in doctoral students. Graduate work can be isolating and stressful. Luckily your health insurance usually includes counseling sessions. TAKE THEM if you need them. Do not be ashamed. You may be surprised with who else is getting them. (I found out that everyone in my cohort, including me, was getting mental health counseling at a certain point.) Exercise can help, as can taking that mental health day once a week and just chilling. Don't be surprised if you get the blues…

-…but be self-aware and able to recognize when the depression is clouding your ability to function. Doctoral programs have a 50% attrition rate, and this is rarely because that 50% is less intelligent than, less motivated than, less driven than, or less ambitious than the other 50% that stays. Often they realize that they are ridiculously unhappy in the field, or that they don't need the degree anymore, or that they'd rather focus on other things in life, or their interests have changed. All of this is okay!

-You will, at some point, be like "eff this, I'm leaving." I think almost every doctoral student has thought about dropping out and just kicking this all to the curb. You need to listen to yourself, and find out whether it is idle thought (nothing to worry about, very normal) or whether you are truly unhappy to the point that you need to leave. Counseling can help you figure this out.

-Don't be afraid to take a semester or a year off if you need to. That's what leaves of absence are for.

Lastly, and positively…

…graduate school is great! Seriously, when else will you ever have the time to study what you want for hours on end, talk to just as interested others about it, and live in an intellectual community of scholars and intellectuals? And occasionally wake up at 11 am and go to the bank at 2 pm? Sometimes you will want to pull out all of your hair but most of the time, you will feel fulfilled and wonderfully encouraged and edified. So enjoy this time!

I work in industry. While a postdoc won't hurt you, it's certainly not necessary for the vast majority of non-academic positions. There are some non-academic positions that function pretty similarly to academic ones, and some of those might prefer a postdoc (think think tanks or policy institutes). But for the vast majority of non-academic jobs - especially if they are not research roles - not having done a postdoc is totally fine.
Second, if I want to gain industry experience while still in graduate school, what might be some recommended ways to go about it? My research focuses on questions of development in Latin America so I'm considering incorporating ethnographic fieldwork not only at my research site but with NGOs/development agencies working in my geographic area of interest to see another side of things. Would this be the best way to go about it or should I consider internships as well?
Both? This doesn't have to be an either/or; if you are considering non-academic careers, you should get any kind of industry experience you can in graduate school. Working with NGOs/nonprofits/other agencies while doing your fieldwork is an excellent way; you can build connections and demonstrate your research skills. I know several people in social sciences who have gotten non-academic jobs this way. But you should also consider internships as well.
Lastly, and maybe this is more personalized to different jobs/fields, but for any of you who are now working outside academia, do you feel that you're still able to do enough research, apply the skills you learned through your PhD, etc. in your non-academic position? 
It's definitely dependent on what you do. I'm a research manager at a tech company, and I definitely apply the skills I learned in my PhD - both the "hard skills" of statistics, research methodology, etc. and the "soft skills" of critical thinking, time management, planning and executing on a giant project, prioritization, communication, conflict resolution, etc. I would say that the latter set of "soft skills" has been FAR more important in the long run for my success here, and I actually work in a direct research role. I do less research myself now that I am a manager - I manage other researchers - but my research skills are still necessary so that I can advise them and direct their work for maximum impact. I also do research project planning that can be multi-year and cover large strategic areas of the business, so that research agenda planning that your PhD teaches you (perhaps indirectly) - that's super useful, too. Surprisingly, grant-writing was useful, too. Not because I write grants here, but because learning to budget what you need to get your work done and learning how to ask for money and resources that you need is a generally useful skill in business, and I now do that all the time.

About your dog: I think that depends entirely on you and your program. I am in a social science program where the majority of my analysis and writing can be done from home, and I prefer to work from home or from a library (as opposed to my cube in the windowless cube farm). When I was taking classes I was generally there from 9-6 or so, but now that my coursework is finished I am rarely at the school itself. I go for meetings, seminars, interesting kinds of things and I do most of my work remotely. My time is verrry flexible, and if my building didn't prohibit it I would get a dog in a heartbeat.

-Find your happy place, something that keeps you the you you were when you came in. I love working out. It gives me energy and I feel good. I stay healthy. I also love reading fiction, so sometimes I just curl up with a good book, work be damned. You have to give yourself permission to not think about work, at least for a couple of hours a week. You may also discover new hobbies! (I never worked out before I came to graduate school.)

-Your work will creep into all aspects of your life, if you let it. This is why I hate unstructured time. You will feel guilty for not doing something, because in graduate school, there is ALWAYS something you can do. ALWAYS. But since there will always be more work, there's no harm in putting it aside for tomorrow, as long as you don't have a deadline.

-You may need to reach outside of your cohort for a social life. None of my close friends are in my doctoral cohort. I've met master's students in my program, master's students in other programs, and I know a few non-graduate students I hang out with, too. Go to graduate student mixers. (If your university doesn't have any, organize some, if you like planning parties.) Join a student group that doesn't take up too much time. I had a doctoral acquaintance who kinda laughed at me because I joined some student groups other than the doctoral student one, and I was usually the only doctoral student in those groups, but I met some close friends (and future job contacts) and had a good time.

-DO NOT FEEL GUILTY FOR WANTING A LIFE OUTSIDE OF GRADUATE SCHOOL. This is paramount. This is important. You are a well-rounded, complex, multifaceted human being. NEVER feel bad for this. Everybody wants some kind of life outside of work. Yes, you may loooove your field, but that doesn't mean you want to do it all day long. Some other doctoral students, and perhaps professors, may make you feel bad about this. Don't let them. Just smile and nod. Then disappear when you need to.

Career:
-This is job preparation. Remember that from Day One. Always be looking for ways to enhance your skills. Read job ads and find out what's hot in your field, what's necessary, what's in demand. For example, in my field statistics and methods are a hot commodity, and they're not a passing fad. I happen to really like statistics and methods, so I have pursued that as a concentration of mine.

-Don't be afraid to take on volunteer work and part-time gigs that will give you skills that will be useful both inside academia and out, as long as it's not against your contract. Your adviser may be against it, but he doesn't have to know as long as it doesn't interfere with your work.

-If you want to work outside of academia - if you are even *considering* the possibility - please please definitely do the above. Even if you aren't considering it, consider the possibility that you won't get a tenure-track job out the box and that you may need to support yourself doing something else for a while. You will have to prove to employers that you have developed usable, useful skills and this is one of the easiest ways to do it. But don't overdo it - get the degree done.

-For more academic related ones - always look for opportunities to present and publish. Presentations look good on your CV. Publications look better. When you write seminar papers, wonder if you can publish them with some revision. Write your seminar papers on what you maybe think you may want to do your dissertation on. Even if you look at them three years later and think "these suck," you can at least glean some useful references and pieces from them. Discuss publication with your adviser early and often, and if you have the time and desire, seek out publication options with other professors and researchers. But if you commit to a project, COMMIT. You don't want to leave a bad impression.

-If you can afford it, occasionally go to conferences even if you aren't presenting. You can network, and you can hear some interesting talks, and you may think about new directions for your own research. You can also meet people who may tell you about jobs, money, opportunities, etc.

-Always try to get someone else to pay for conference travel before you come out of pocket. Including your adviser. Do not be shy about asking if he or she can pay. If he can't, he'll just say no. Usually the department has a travel fund for students, but often it's only if you are presenting.

-If you are interested in academia, you should get some teaching experience. There are two traditional ways to do this: TAing a course, and teaching as a sole instructor. If you can help it, I wouldn't recommend doing a sole instructor position until you are finished with coursework. Teaching takes a LOT of time to do right. You should definitely TA at least one course, and probably a few different ones. But don't overdo it, if you can help it, because again, it takes a LOT of time. More than you expect at the outset. If you are in the humanities, I think sole instructor positions are very important for nabbing jobs so when you are in the exam/ABD phase, you may want to try at least one. If your own university has none, look at adjuncting for nearby colleges, including community colleges. (I would wager that the majority of natural science/physical science students, and most social science students, have never sole taught a class before they get an assistant professor job. At least, it's not that common n my field, which straddles the social and natural sciences.)

-Always look for money. Money is awesome. If you can fund yourself you can do what you want, within reason. Your university will be thrilled, your adviser will be happy, and you can put it on your CV. It's win-win-win! Don't put yourself out of the running before anyone else has a chance to. Apply even if you think you won't get it or the odds are against you (they always are), as long as you are eligible. Apply often. Apply even if it's only $500. (That's conference travel!) Money begets money. The more awards you get, the more awards you will get. They will get bigger over time. If you are in the sciences and social sciences, you should get practice writing at least one grant. You don't have to write the whole thing, but at least get in on the process so that you can see how it's done. Grant-writing is very valuable both in and outside of graduate school.

-Revise your CV every so often. Then look and decide what you want to add to it. Then go get that thing, so you can add it.

-The career office at big universities is often not just for undergrads. I was surprised to learn that my career center offers help on CV organization and the academic job search, as well as alternative/non-academic career searches for doctoral students. In fact, there are two people whose sole purpose it is to help PhD students find nonacademic careers, and they both have PhDs. This will vary by university - some universities will have very little for grad students. Find out before you write the office off.

-It's never too early to go to seminars/workshops like "the academic job search inside and out", "creating the perfect CV," "getting the job," etc. NEVER. Often the leader will share tips that are more aimed towards early graduate students, or tidbits that are kind of too late for more advanced students to take care of. This will also help you keep a pulse on what's hot in your field. It'll help you know what lines you need to add to your CV. And they're interesting.

Other:

-Decide ahead of time what you are NOT willing to sacrifice on the altar of academia. Then stick to it.
I'm serious. If you decide that you do NOT want to sacrifice your relationship, don't. If it's your geographical mobility, don't. I mean, be realistic, and realize that there will always be trade-offs. But you have to think about what's important to you for your quality of life, and realize that there is always more to you than graduate school.

-If you don't want to be a professor, do not feel guilty about this. At all. Zero. However, you will have to do things differently than most doctoral students. Your adviser will probably never have worked outside of the academy (although this may vary depending on the field) so he may or may not be able to help you. But you have a special mission to seek out the kinds of experiences that will help you find a non-academic job. Test the waters with your adviser before you tell him this. My adviser was quite amenable to it, but that's because I told him that my goal was to still do research and policy work in my field just not at a university, AND because it's quite common in my field for doctoral students to do non-academic work. If you're in a field where it's not common (or where your professors refuse to believe it's common, or it's not supposed to be common)…well, you may be a little more on your own.

-Every so often, you will need to reflect on the reasons you came to graduate school. Sometimes, just sit and think quietly. Why are you doing this to yourself? Do you love your field? Do you need this degree to do what you want to do? Usually the answer is yes and yes, and usually you'll keep on trucking. But sometimes when the chips are down you will need to reevaluate why you put yourself through this in the first place.

-To my great dismay, depression is quite common in doctoral students. Graduate work can be isolating and stressful. Luckily your health insurance usually includes counseling sessions. TAKE THEM if you need them. Do not be ashamed. You may be surprised with who else is getting them. (I found out that everyone in my cohort, including me, was getting mental health counseling at a certain point.) Exercise can help, as can taking that mental health day once a week and just chilling. Don't be surprised if you get the blues…

-…but be self-aware and able to recognize when the depression is clouding your ability to function. Doctoral programs have a 50% attrition rate, and this is rarely because that 50% is less intelligent than, less motivated than, less driven than, or less ambitious than the other 50% that stays. Often they realize that they are ridiculously unhappy in the field, or that they don't need the degree anymore, or that they'd rather focus on other things in life, or their interests have changed. All of this is okay!

-You will, at some point, be like "eff this, I'm leaving." I think almost every doctoral student has thought about dropping out and just kicking this all to the curb. You need to listen to yourself, and find out whether it is idle thought (nothing to worry about, very normal) or whether you are truly unhappy to the point that you need to leave. Counseling can help you figure this out.

-Don't be afraid to take a semester or a year off if you need to. That's what leaves of absence are for.

Lastly, and positively…

…graduate school is great! Seriously, when else will you ever have the time to study what you want for hours on end, talk to just as interested others about it, and live in an intellectual community of scholars and intellectuals? And occasionally wake up at 11 am and go to the bank at 2 pm? Sometimes you will want to pull out all of your hair but most of the time, you will feel fulfilled and wonderfully encouraged and edified. So enjoy this time!

I don't know if you've sent the email yet, but for posterity, here are my thoughts. I am a hiring manager in industry.
1) The entire email is unnecessary. They haven't forgotten that you interviewed, and if they have not contacted you yet, that means that you haven't gotten an offer (yet). The best thing to do after having already sent a follow-up thank-you email is to move on until/unless the company contacts you.
2) If one insists on sending a follow-up email, it should be short. If I'm hiring for a position, I am doing that on top of my already demanding job, and my time for reading emails is limited. Not going to lie, if I opened this one, I'd very quickly scan it then immediately close it. (Or if I have time, I might respond with a quick "Thanks for your contact, no decisions have been made yet, sit tight until we reach out.")
I know that this is contrary to what a lot of career sites say, but in my experience as an actual hiring manager, these second follow-up emails are never helpful. I already know that you're qualified for the role; we interviewed you. I don't need people to reiterate the skills that they would bring to the role especially after we've already interviewed them, because we've already made a judgment on that either way. Presumably, all this was either on your cover letter or resume when you applied and/or we talked about in your interview. Ironically, the only thing that is useful in the mail is hearing that are you still interested and excited in the position (e.g., you don't have another offer that I have to worry about competing with somewhere else, or that this is still a role at the top of your list.)
If you insist upon sending a follow up, I'd suggest that you cut it to this.
 
Dear [INTERVIEWER 1] and [INTERVIEWER 2],
I hope you had a great weekend! Thank you again for taking the time to meet with me on [DATE] and for considering me for the [NAME OF POSITION] position.
I wanted to follow-up regarding my interview. I so enjoyed getting to know your team and learning more about the role; I am really excited about the prospect of this position. May I inquire as to when you might have a decision? <- because let's be real, this is what you really want to know.
Please don't hesitate to contact me if you have any questions! I can be reached at [PHONE NUMBER] or via email at .
Thank you once again for your time and consideration.
Sincerely,

I work in industry. While a postdoc won't hurt you, it's certainly not necessary for the vast majority of non-academic positions. There are some non-academic positions that function pretty similarly to academic ones, and some of those might prefer a postdoc (think think tanks or policy institutes). But for the vast majority of non-academic jobs - especially if they are not research roles - not having done a postdoc is totally fine.
Second, if I want to gain industry experience while still in graduate school, what might be some recommended ways to go about it? My research focuses on questions of development in Latin America so I'm considering incorporating ethnographic fieldwork not only at my research site but with NGOs/development agencies working in my geographic area of interest to see another side of things. Would this be the best way to go about it or should I consider internships as well?
Both? This doesn't have to be an either/or; if you are considering non-academic careers, you should get any kind of industry experience you can in graduate school. Working with NGOs/nonprofits/other agencies while doing your fieldwork is an excellent way; you can build connections and demonstrate your research skills. I know several people in social sciences who have gotten non-academic jobs this way. But you should also consider internships as well.
Lastly, and maybe this is more personalized to different jobs/fields, but for any of you who are now working outside academia, do you feel that you're still able to do enough research, apply the skills you learned through your PhD, etc. in your non-academic position? 
It's definitely dependent on what you do. I'm a research manager at a tech company, and I definitely apply the skills I learned in my PhD - both the "hard skills" of statistics, research methodology, etc. and the "soft skills" of critical thinking, time management, planning and executing on a giant project, prioritization, communication, conflict resolution, etc. I would say that the latter set of "soft skills" has been FAR more important in the long run for my success here, and I actually work in a direct research role. I do less research myself now that I am a manager - I manage other researchers - but my research skills are still necessary so that I can advise them and direct their work for maximum impact. I also do research project planning that can be multi-year and cover large strategic areas of the business, so that research agenda planning that your PhD teaches you (perhaps indirectly) - that's super useful, too. Surprisingly, grant-writing was useful, too. Not because I write grants here, but because learning to budget what you need to get your work done and learning how to ask for money and resources that you need is a generally useful skill in business, and I now do that all the time.

About your dog: I think that depends entirely on you and your program. I am in a social science program where the majority of my analysis and writing can be done from home, and I prefer to work from home or from a library (as opposed to my cube in the windowless cube farm). When I was taking classes I was generally there from 9-6 or so, but now that my coursework is finished I am rarely at the school itself. I go for meetings, seminars, interesting kinds of things and I do most of my work remotely. My time is verrry flexible, and if my building didn't prohibit it I would get a dog in a heartbeat. Another thing to keep in mind: a dog can be a great comfort when you're all stressed out over graduate school.

Advice?

Age:
-Don't feel like you have nothing to offer just because you are younger. I was 22 when I started graduate school. You got accepted to the program for a reason, and chances are you are just as equipped as any older students are to successfully complete the program, just in a different way.

-Your older classmates may be just as terrified as you. Talk to them. You have a lot in common. You are, after all, in the same place.

-You will feel like an imposter, like you don't belong, or like you are constantly behind. Or all three. It's normal. It will pass. (Well, sort of.) People of all ages go through this.

Adviser related:
-If you are lucky enough to get both research interest fit and personality fit perfect, congratulations! But sometimes, personality fit is more important than research interest fit as long as the research isn't too different. A great adviser is interested in your career development, likes you as a person, advocates for you, and wants to hear your ideas. Even if his or her research is quite different from yours, they may give you the autonomy to work on your own projects and just supervise you. A bad personality fit will drive you nuts, even if you love his or her research. Consider that when evaluating your adviser fit. (This will vary by field: research fit may be less important in the humanities, more important in the natural and physical sciences. Social sciences are somewhere in-between.)

-Don't be afraid to be straight up blunt with your adviser when it comes to asking about your progress. Ask if you are where you should be both academic program wise and getting-a-job-after-this-mess-wise.

-Be proactive. Advisers love when you draw up an agenda for your one-on-one meetings, come with talking points and progress to share, have concrete questions to ask, and have overall shown that you have been thoughtful and taken control of your own program. Of course, this won't immediately come easily to you, but in time you will work up to it. Every semester I type up my semester goals, and at the beginning of the year I type up annual goals. I show them to my adviser and we talk about whether they are too ambitious, or whether I need to revise them, and how I can meet them.

-Don't expect your adviser to actually know what courses you have to take to graduate. They will know about comprehensive exams and the dissertation, but a lot of professors don't really keep up with the course requirements, especially if their program is in flux. Get you a student handbook, and find out what you need to take. Map it out in a grid, and check off things when you finish them. Show this to your adviser every semester. You may have to explain how such and such class fills a requirement.

-Nobody loves you as much as you, except your mother. Keep this in mind as you take in advice from all sources, including your adviser. Your adviser is there to guide you, but that doesn't mean you have to do everything he says.

Studying:
-You will have to read more than you ever did before, in less time than you ever have before, and you will be expected to retain more than you ever have before. The way that you studied in undergrad may need some tweaking. Be prepared for this.

-Corollary: you may find that your methods change with age or interests or time. I preferred to study alone in college, but in grad school, I prefer to study in groups. It keeps me on task and the socialization keeps me motivated. You may find that you shift from being a more auditory learner to a visual learner or whatever.

-You will feel behind at first. This is normal.

-At some point you will realize that your professors don't actually expect you to read everything they assign you. This, of course, will vary by program, but there will be at least one class where the reading is actually impossible to do in one week. The point is to read enough that you know the major themes and can talk intelligently about them, and then pick some of the readings to really dig into and think more deeply about.

-For most programs, don't worry so much about grades. If you stay on top of your work and do what you're supposed to, you will probably get an A. How much grades matter varies from program to program. In some programs, a B is a signal that you are not up to par, and more than a few Bs will warrant a discussion with your adviser or the DGS. My program isn't like that - A, B, it's all meaningless. My adviser doesn't even know what my grades are. But at almost all programs, a C means you need to retake the course, and two Cs means you have to convince the DGS not to kick you out.

Extracurricular activity: What's that? No, seriously:
-A lot of your time will be unstructured. You will have coursework, but most grad classes meet once a week for two hours and you may have three classes. You may have meetings with your adviser every so often and some seminars or things to catch (like we have grand rounds and colloquia that are required), but a lot of time will be unstructured. However, since you have so much more work than you had in undergrad, you actually will have less free time than you had in undergrad. This may initially cause you great anxiety. It did for me. Some people love unstructured time, though. (I don't.)

-Because of this, you'll have to be planful about your non-grad school related stuff.

-TAKE TIME OFF. DO it. It's important for your mental health. However you do it doesn't matter. Some people work it like a 9-5 job. Some people take a day off per week (me) and maybe a few hours spread across the week. Some people work half days 7 days a week. However you do it, there needs to be a time when you say "f this, I'm going to the movies."

-Find your happy place, something that keeps you the you you were when you came in. I love working out. It gives me energy and I feel good. I stay healthy. I also love reading fiction, so sometimes I just curl up with a good book, work be damned. You have to give yourself permission to not think about work, at least for a couple of hours a week. You may also discover new hobbies! (I never worked out before I came to graduate school.)

-Your work will creep into all aspects of your life, if you let it. This is why I hate unstructured time. You will feel guilty for not doing something, because in graduate school, there is ALWAYS something you can do. ALWAYS. But since there will always be more work, there's no harm in putting it aside for tomorrow, as long as you don't have a deadline.

-You may need to reach outside of your cohort for a social life. None of my close friends are in my doctoral cohort. I've met master's students in my program, master's students in other programs, and I know a few non-graduate students I hang out with, too. Go to graduate student mixers. (If your university doesn't have any, organize some, if you like planning parties.) Join a student group that doesn't take up too much time. I had a doctoral acquaintance who kinda laughed at me because I joined some student groups other than the doctoral student one, and I was usually the only doctoral student in those groups, but I met some close friends (and future job contacts) and had a good time.

-DO NOT FEEL GUILTY FOR WANTING A LIFE OUTSIDE OF GRADUATE SCHOOL. This is paramount. This is important. You are a well-rounded, complex, multifaceted human being. NEVER feel bad for this.

I'm curious - why do you have two Fs when you withdrew from the program? Is it because you didn't withdraw properly from the program and just stopped going to class?
I'd try to mitigate this on two fronts. Once, go back to the university where you tried that master's degree and I'd try to administratively get those Fs changed into Ws. I'd explain the situation to the registrar, perhaps providing some sort of evidence/proof of what happened. There's nothing wrong with withdrawing from a master's program once realizing it's not for you. And it doesn't sound like you couldn't handle the work, only that you were disinterested in completing it.
If that doesn't work, or will be too slow to make a significant difference, you can write a supplemental essay explaining that the Fs were a result of you withdrawing improperly from the program. I like the bit about how the experience motivated you to go into advising in the first place, so that might support this case, too.

If I were you, I'd leave academia and find something else.
As was mentioned, a PhD doesn't provide job security and a road to financial security. Not in and of itself, and definitely not in the arts and humanities. Academia in those areas is really tight with a much larger supply than demand. And although you can definitely do things with a PhD in the arts and/or humanities outside of academia, those jobs are largely not made for nor exclusive to people with PhDs in those fields. You could probably do them with the degrees you currently have.
I am a non-academic industry researcher. I did finish my PhD (I had this crisis inside of graduate school, and ultimately decided to finish) but when I was having the crisis, I loved the same things you love and disliked the same thing you dislike. My current job, NOT in academia, offers me a lot of the things that I liked - just in different formats than what I expected. I don't "teach" in the traditional sense (and not college students), but I manage people and I have lots of opportunities for teaching and advising in different formats (career development for my direct reports, teaching seminars and sessions at work, teaching my client/partner teams about research and different topics areas). I am more than supported if I want to go to conferences - I turn down travel opportunities - and I spend a lot of time writing and doing research. I've found that there are lots of jobs outside of academia that allow you to do one or more of these things, if you broaden your definition - or already have a pretty broad one - of how to scratch those itches.
And if you like practical applications, to me that sounds like even more reason to look for non-academic work. You'll only miss that more in graduate school. I got my PhD in public health, and I sorely missed that all throughout - while I loved the research, I wanted to do more of the health education and promotion myself as well.
I think the question now is - what do you want to do? It's easier to narrow yourself down to a couple of areas than it is to open the floodgates. Check out Versatile PhD if you haven't already, and get some suggestions there for things that folks from the arts and humanities do after leaving academia (they do a LOT of different things!). Do you want to continue doing research/scholarship in the humanities, or are you willing (or wanting) to go completely different? Do you want nonprofit/NGO/government agency type work or would you be happy to work in the private sector too? (They're not mutually exclusive, but I knew a lot of academics who were reluctant to work at for-profit corporations post-grad school.)

It's very common to feel sudden anxiety and I think that rises as you get closer to the first day, so you're in good company!
I had a similar conundrum to you when I first entered graduate school. I was getting a PhD in an interdisciplinary social sciences field, but I really wanted to teach in the discipline I got my bachelor's degree in (which my PhD research was focused on). I spent a ton of time and energy trying to figure out the best course of action.
I don't know much about communications specifically, as that's not my field. But what I have absorbed is that interdisciplinary fields tend to be less precious about the exact kind of PhD that you got and more concerned about what you do research on and what you can teach. This also varies a lot by the university. I've noticed communications departments are all over the place: some are professional programs that focus on the technical aspects of communication (and really are more focused on media, like radio/tv/film); some focus on corporate communications in business; others are far broader and take a more humanistic approach to communication, including elements of visual culture as well. Some departments basically include media studies too.
Whether or not it would be helpful to take the elective depends a lot. I don't think one random class would qualify you to teach quant methods, so it won't be useful in that regard. However, if you were interested in mixed-methods research or incorporating quant research into your research - or even just using that as a stepping stone into more depth in the area - it could be useful. IMO, though, your plans to expand your research to look at digital studies and global media is probably going to be more beneficial to your career plans than a single quant methods class, especially if you don't plan to do any quant research.
Your second question, I think, depends on the orientation of the department. Some folks, when they say "qualitative methods," are referring specifically to things like interviews, focus groups, ethnography, etc. Others mean it more expansively and include the kind of scholarship humanists do. You'd basically have to evaluate each department to get a sense of what they mean when they're looking for candidates that focus on those areas.

Also, I don't think this is insecurity at all. You should definitely talk to your department about it! You can bring it up with your adviser once you've established a relationship.

I wrote my methods section first, because it was the easiest to write and by the time I was writing, I had already finished my data collection. I was doing data analysis simultaneously, so that part happened more iteratively - as I conducted my analyses I went back and edited sections to make them accurate to what I did.
I wrote the results next, as that was second-easiest. Methods, data analysis, and results altogether took me from early September through mid-December to complete (including reviews of drafts and consultation with my advisers), so around 2.5 months.
I wrote the intro/literature review next. (In mine, the intro and the literature review are two separate sections, but the intro is very short - like 6 pages). It took me about 2-3 months to do this, so I worked on it from January to March-ish. It was easier to do this because now I knew what I was introducing, so I tailored my lit review to refer very specifically to previous research/theoretical work that pointed to the precise kind of research and analyses I ended up doing. If you write your lit review before doing your methods and results, you may have to go back and edit a lot to tailor your lit review to your work.
I didn't do an iterative review process with this - I drafted the entire thing and sent it as a huge complete chunk to my adviser. Perhaps risky, but I knew from previous experience that I wouldn't have months and months of comments back, so that's what I did.
Then I wrote the discussion. This was the hardest part to write for me and I hated it, but I think it took me about a month - so I was done in April-ish.
That was just enough time for me to get the comments from my lit review back, which I addressed in like 2-3 weeks, and then comments for my discussion, which I also addressed in maybe 1-2 weeks. I did not update my lit review unless I was aware that a new work had been published - so I didn't go looking for works that had been published in the last 2 months since I had submitted my draft. But I was receiving article alerts from journals and people also sometimes sent me articles, so if I received something and I knew where it would fit well, I wove it in.

If I were you, I'd leave academia and find something else.

About your dog: I think that depends entirely on you and your program. I am in a social science program where the majority of my analysis and writing can be done from home, and I prefer to work from home or from a library (as opposed to my cube in the windowless cube farm). When I was taking classes I was generally there from 9-6 or so, but now that my coursework is finished I am rarely at the school itself. I go for meetings, seminars, interesting kinds of things and I do most of my work remotely. My time is verrry flexible, and if my building didn't prohibit it I would get a dog in a heartbeat. Another thing to keep in mind: a dog can be a great comfort when you're all stressed out over graduate school.

Advice?

Age:
-Don't feel like you have nothing to offer just because you are younger. I was 22 when I started graduate school. You got accepted to the program for a reason, and chances are you are just as equipped as any older students are to successfully complete the program, just in a different way.

-Your older classmates may be just as terrified as you. Talk to them. You have a lot in common. You are, after all, in the same place.

-You will feel like an imposter, like you don't belong, or like you are constantly behind. Or all three. It's normal. It will pass. (Well, sort of.) People of all ages go through this.

Adviser related:
-If you are lucky enough to get both research interest fit and personality fit perfect, congratulations! But sometimes, personality fit is more important than research interest fit as long as the research isn't too different. A great adviser is interested in your career development, likes you as a person, advocates for you, and wants to hear your ideas. Even if his or her research is quite different from yours, they may give you the autonomy to work on your own projects and just supervise you. A bad personality fit will drive you nuts, even if you love his or her research. Consider that when evaluating your adviser fit. (This will vary by field: research fit may be less important in the humanities, more important in the natural and physical sciences. Social sciences are somewhere in-between.)

-Don't be afraid to be straight up blunt with your adviser when it comes to asking about your progress. Ask if you are where you should be both academic program wise and getting-a-job-after-this-mess-wise.

-Be proactive. Advisers love when you draw up an agenda for your one-on-one meetings, come with talking points and progress to share, have concrete questions to ask, and have overall shown that you have been thoughtful and taken control of your own program. Of course, this won't immediately come easily to you, but in time you will work up to it. Every semester I type up my semester goals, and at the beginning of the year I type up annual goals. I show them to my adviser and we talk about whether they are too ambitious, or whether I need to revise them, and how I can meet them.

-Don't expect your adviser to actually know what courses you have to take to graduate. They will know about comprehensive exams and the dissertation, but a lot of professors don't really keep up with the course requirements, especially if their program is in flux. Get you a student handbook, and find out what you need to take. Map it out in a grid, and check off things when you finish them. Show this to your adviser every semester. You may have to explain how such and such class fills a requirement.

-Nobody loves you as much as you, except your mother. Keep this in mind as you take in advice from all sources, including your adviser. Your adviser is there to guide you, but that doesn't mean you have to do everything he says.

Studying:
-You will have to read more than you ever did before, in less time than you ever have before, and you will be expected to retain more than you ever have before. The way that you studied in undergrad may need some tweaking. Be prepared for this.

-Corollary: you may find that your methods change with age or interests or time. I preferred to study alone in college, but in grad school, I prefer to study in groups. It keeps me on task and the socialization keeps me motivated. You may find that you shift from being a more auditory learner to a visual learner or whatever.

-You will feel behind at first. This is normal.

-At some point you will realize that your professors don't actually expect you to read everything they assign you. This, of course, will vary by program, but there will be at least one class where the reading is actually impossible to do in one week. The point is to read enough that you know the major themes and can talk intelligently about them, and then pick some of the readings to really dig into and think more deeply about.

-For most programs, don't worry so much about grades. If you stay on top of your work and do what you're supposed to, you will probably get an A. How much grades matter varies from program to program. In some programs, a B is a signal that you are not up to par, and more than a few Bs will warrant a discussion with your adviser or the DGS. My program isn't like that - A, B, it's all meaningless. My adviser doesn't even know what my grades are. But at almost all programs, a C means you need to retake the course, and two Cs means you have to convince the DGS not to kick you out.

Extracurricular activity: What's that? No, seriously:
-A lot of your time will be unstructured. You will have coursework, but most grad classes meet once a week for two hours and you may have three classes. You may have meetings with your adviser every so often and some seminars or things to catch (like we have grand rounds and colloquia that are required), but a lot of time will be unstructured. However, since you have so much more work than you had in undergrad, you actually will have less free time than you had in undergrad. This may initially cause you great anxiety. It did for me. Some people love unstructured time, though. (I don't.)

-Because of this, you'll have to be planful about your non-grad school related stuff.

-TAKE TIME OFF. DO it. It's important for your mental health. However you do it doesn't matter. Some people work it like a 9-5 job. Some people take a day off per week (me) and maybe a few hours spread across the week. Some people work half days 7 days a week. However you do it, there needs to be a time when you say "f this, I'm going to the movies."

-Find your happy place, something that keeps you the you you were when you came in. I love working out. It gives me energy and I feel good. I stay healthy. I also love reading fiction, so sometimes I just curl up with a good book, work be damned. You have to give yourself permission to not think about work, at least for a couple of hours a week. You may also discover new hobbies! (I never worked out before I came to graduate school.)

-Your work will creep into all aspects of your life, if you let it. This is why I hate unstructured time. You will feel guilty for not doing something, because in graduate school, there is ALWAYS something you can do. ALWAYS. But since there will always be more work, there's no harm in putting it aside for tomorrow, as long as you don't have a deadline.

-You may need to reach outside of your cohort for a social life. None of my close friends are in my doctoral cohort. I've met master's students in my program, master's students in other programs, and I know a few non-graduate students I hang out with, too. Go to graduate student mixers. (If your university doesn't have any, organize some, if you like planning parties.) Join a student group that doesn't take up too much time. I had a doctoral acquaintance who kinda laughed at me because I joined some student groups other than the doctoral student one, and I was usually the only doctoral student in those groups, but I met some close friends (and future job contacts) and had a good time.

-DO NOT FEEL GUILTY FOR WANTING A LIFE OUTSIDE OF GRADUATE SCHOOL. This is paramount. This is important. You are a well-rounded, complex, multifaceted human being. NEVER feel bad for this. Everybody wants some kind of life outside of work. Yes, you may loooove your field, but that doesn't mean you want to do it all day long. Some other doctoral students, and perhaps professors, may make you feel bad about this. Don't let them. Just smile and nod. Then disappear when you need to.

Career:
-This is job preparation. Remember that from Day One. Always be looking for ways to enhance your skills. Read job ads and find out what's hot in your field, what's necessary, what's in demand. For example, in my field statistics and methods are a hot commodity, and they're not a passing fad. I happen to really like statistics and methods, so I have pursued that as a concentration of mine.

-Don't be afraid to take on volunteer work and part-time gigs that will give you skills that will be useful both inside academia and out, as long as it's not against your contract. Your adviser may be against it, but he doesn't have to know as long as it doesn't interfere with your work.

-If you want to work outside of academia - if you are even *considering* the possibility - please please definitely do the above. Even if you aren't considering it, consider the possibility that you won't get a tenure-track job out the box and that you may need to support yourself doing something else for a while. You will have to prove to employers that you have developed usable, useful skills and this is one of the easiest ways to do it. But don't overdo it - get the degree done.

-For more academic related ones - always look for opportunities to present and publish. Presentations look good on your CV. Publications look better. When you write seminar papers, wonder if you can publish them with some revision. Write your seminar papers on what you maybe think you may want to do your dissertation on. Even if you look at them three years later and think "these suck," you can at least glean some useful references and pieces from them. Discuss publication with your adviser early and often, and if you have the time and desire, seek out publication options with other professors and researchers. But if you commit to a project, COMMIT. You don't want to leave a bad impression.

-If you can afford it, occasionally go to conferences even if you aren't presenting. You can network, and you can hear some interesting talks, and you may think about new directions for your own research. You can also meet people who may tell you about jobs, money, opportunities, etc.

-Always try to get someone else to pay for conference travel before you come out of pocket. Including your adviser. Do not be shy about asking if he or she can pay. If he can't, he'll just say no. Usually the department has a travel fund for students, but often it's only if you are presenting.

-If you are interested in academia, you should get some teaching experience. There are two traditional ways to do this: TAing a course, and teaching as a sole instructor. If you can help it, I wouldn't recommend doing a sole instructor position until you are finished with coursework. Teaching takes a LOT of time to do right. You should definitely TA at least one course, and probably a few different ones. But don't overdo it, if you can help it, because again, it takes a LOT of time. More than you expect at the outset. If you are in the humanities, I think sole instructor positions are very important for nabbing jobs so when you are in the exam/ABD phase, you may want to try at least one. If your own university has none, look at adjuncting for nearby colleges, including community colleges. (I would wager that the majority of natural science/physical science students, and most social science students, have never sole taught a class before they get an assistant professor job. At least, it's not that common n my field, which straddles the social and natural sciences.)

-Always look for money. Money is awesome. If you can fund yourself you can do what you want, within reason. Your university will be thrilled, your adviser will be happy, and you can put it on your CV. It's win-win-win! Don't put yourself out of the running before anyone else has a chance to. Apply even if you think you won't get it or the odds are against you (they always are), as long as you are eligible. Apply often. Apply even if it's only $500. (That's conference travel!) Money begets money. The more awards you get, the more awards you will get. They will get bigger over time. If you are in the sciences and social sciences, you should get practice writing at least one grant. You don't have to write the whole thing, but at least get in on the process so that you can see how it's done. Grant-writing is very valuable both in and outside of graduate school.

-Revise your CV every so often. Then look and decide what you want to add to it. Then go get that thing, so you can add it.

-The career office at big universities is often not just for undergrads. I was surprised to learn that my career center offers help on CV organization and the academic job search, as well as alternative/non-academic career searches for doctoral students. In fact, there are two people whose sole purpose it is to help PhD students find nonacademic careers, and they both have PhDs. This will vary by university - some universities will have very little for grad students. Find out before you write the office off.

-It's never too early to go to seminars/workshops like "the academic job search inside and out", "creating the perfect CV," "getting the job," etc. NEVER. Often the leader will share tips that are more aimed towards early graduate students, or tidbits that are kind of too late for more advanced students to take care of. This will also help you keep a pulse on what's hot in your field. It'll help you know what lines you need to add to your CV. And they're interesting.

Other:

-Decide ahead of time what you are NOT willing to sacrifice on the altar of academia. Then stick to it.
I'm serious. If you decide that you do NOT want to sacrifice your relationship, don't. If it's your geographical mobility, don't. I mean, be realistic, and realize that there will always be trade-offs. But you have to think about what's important to you for your quality of life, and realize that there is always more to you than graduate school.

-If you don't want to be a professor, do not feel guilty about this. At all. Zero. However, you will have to do things differently than most doctoral students. Your adviser will probably never have worked outside of the academy (although this may vary depending on the field) so he may or may not be able to help you. But you have a special mission to seek out the kinds of experiences that will help you find a non-academic job. Test the waters with your adviser before you tell him this. My adviser was quite amenable to it, but that's because I told him that my goal was to still do research and policy work in my field just not at a university, AND because it's quite common in my field for doctoral students to do non-academic work. If you're in a field where it's not common (or where your professors refuse to believe it's common, or it's not supposed to be common)…well, you may be a little more on your own.

-Every so often, you will need to reflect on the reasons you came to graduate school. Sometimes, just sit and think quietly. Why are you doing this to yourself? Do you love your field? Do you need this degree to do what you want to do? Usually the answer is yes and yes, and usually you'll keep on trucking. But sometimes when the chips are down you will need to reevaluate why you put yourself through this in the first place.

-To my great dismay, depression is quite common in doctoral students. Graduate work can be isolating and stressful. Luckily your health insurance usually includes counseling sessions. TAKE THEM if you need them. Do not be ashamed. You may be surprised with who else is getting them. (I found out that everyone in my cohort, including me, was getting mental health counseling at a certain point.) Exercise can help, as can taking that mental health day once a week and just chilling. Don't be surprised if you get the blues…

-…but be self-aware and able to recognize when the depression is clouding your ability to function. Doctoral programs have a 50% attrition rate, and this is rarely because that 50% is less intelligent than, less motivated than, less driven than, or less ambitious than the other 50% that stays. Often they realize that they are ridiculously unhappy in the field, or that they don't need the degree anymore, or that they'd rather focus on other things in life, or their interests have changed. All of this is okay!

-You will, at some point, be like "eff this, I'm leaving." I think almost every doctoral student has thought about dropping out and just kicking this all to the curb. You need to listen to yourself, and find out whether it is idle thought (nothing to worry about, very normal) or whether you are truly unhappy to the point that you need to leave. Counseling can help you figure this out.

-Don't be afraid to take a semester or a year off if you need to. That's what leaves of absence are for.

Lastly, and positively…

…graduate school is great! Seriously, when else will you ever have the time to study what you want for hours on end, talk to just as interested others about it, and live in an intellectual community of scholars and intellectuals? And occasionally wake up at 11 am and go to the bank at 2 pm? Sometimes you will want to pull out all of your hair but most of the time, you will feel fulfilled and wonderfully encouraged and edified. So enjoy this time!

Getting on publications when you're on a project for 2 years or less is very much a matter of luck: you have to enter a project at the exact right time that the research is close to publication BUT is not so close that you don't have time to contribute meaningfully in a way that earns you an authorship. While publications can help you get into PhD programs, they aren't strictly necessary, so I'd focus most of your energy on trying to get into a lab where you can get meaningful research experience.
Getting publications usually happens in one of three rough ways: you work on existing project that a professor, postdoc, or other graduate student is leading and gain authorship by helping conduct the research and/or write the resulting paper; you take a "chunk" of existing research that your PI has lying around and spearhead writing a paper on it, often with other students or postdocs; or you start your own project from scratch and write on it. As a master's student option 3 is usually not easily possible. Option 1 is where the luck really comes in. Option 2 is something you can actually talk to some PIs about when you start working in their lab - whether there are cool semi-independent projects they need someone to finish up or restart. Whether or not they can be finished in time to get a publication submitted by the time you apply to doctoral programs depends a lot on the project itself, but you have better chances of it than with option 3.
One thing I'll note from your post is you seem to have a trend of putting blame on other folks. You maybe are just that unfortunate in that you had a string of "lazy" partners that offloaded their work onto you, an uninterested adviser, and now the trend is just starting up again. But if this is happening to you multiple times across 3+ projects, I'd start to wonder about your own place in all this, and whether there are habits or skills or practices you can engage in to increase the likelihood that you'll finish projects or get a publication.

I'm having a difficult time understanding what the current issue is. It seems that the lab sharing issue has been resolved, and your adviser may have an unpleasant personality characteristic (the student-bashing, although that can be interpreted in many ways) that you can't change. The only issue that really leaves is making sure that you are working on the right project to ensure that you can graduate.
You said:
First, months before starting this project I had a video call meeting with my supervisor and agreed on the topic I will be working on. Considering that season is a factor for the main topic, we both agreed to have a small topic to be busy with while waiting for summer. However, when I had arrived it seems it was made clear to me that I will not be working on that main topic and will be focusing on the small topic instead. Which was already a sign for me to inform my university immediately but I did not since I was too confident that this should not take long and when summer comes, I will be doing on the agreed main topic. But setbacks after setbacks, this small topic is still not done.
It's unclear to me how it was "made clear" that you will be working on the small topic and not the main topic. Regardless, you need to seek clarity. Talk to your supervisor and explicitly ask: "When we first started, we agreed that I'd be working on topic A. But recently, I've still been working on topic B that was supposed to be a pre-summer project only. Do you expect me to finish topic B before I can work on topic A, or can I hand off my project to another student, or is there some other way that I can go back to working on topic A as planned?" or something like that. Get a clear answer from your PI rather than trying to read the tea leaves.
I don't know how a third-party university can limit the number of supervisees your PI has, and two seems unreasonable for a professor who is trying to operate a thriving lab. Are you already concerned about the level of supervision that your PI has given you, or have you already seen evidence that aren't getting what you need? Keep in mind that taking a few weeks for feedback on significant portions of your thesis is very normal in academia, and expecting daily contact with your PI (or even weekly) is going to be unrealistic. What do you feel like you're missing? Have you made explicit requests for support or assistance from your PI based on your actual needs (and are they realistic)? 
I'm not sure what your frustration is about the formal introductions, but that's not really your PI's job? You can easily introduce yourself to new faces in your PI's lab. But again, the problem that seems to have stemmed from that seems resolved.
It's also not your PI's job to "thoroughly check" a student's manuscript to make sure they didn't make analysis errors. That's the student's job. While every PI is going to want to catch egregious mistakes or things that are obviously wrong, they're not going to re-run all of your analyses and make sure that you did the work correctly.  (Or rather, they shouldn't!) At some point, the PI needs to trust that you're going to do the work correctly. If they can't, that probably means fewer projects and authorships for the student they can't trust.
That said, it seems like a running theme is you not checking with the university when things aren't working the way you expect. So instead of writing your manuscript with your fingers crossed, you need to check with your university to make sure that they will accept your work. You don't want to waste a lot of time writing only to find out that your topic won't be accepted.
PhD students don't usually supervise master's students, so assigning you to one of them may not have been appropriate. It could be that she has time and you just have too-high expectations for how much time she can give you. Whether or not she's interested in your topic is more or less irrelevant; the only relevant thing is will she support it.

Oh my goodness, you should not be paying research expenses and travel costs. I’m sorry if that’s not a helpful response but you should know that it’s not normal or expected! I’m curious how your program works; did you apply to work with a specific PI? And if so, did they develop the project with you, and was there any discussion of funding? This is why many programs will not accept students without at least partial guarantee of funding (e.g., a grant your PI has that you will be working under), but I don’t know how it works in your field. Do you have a dissertation committee, and did you go through a research proposal process? I cannot imagine allowing a student to take on an international research project with no funding. At the very least, your advisor and department should be helping you find grants to apply for. 
Unfortunately I think it’s pretty standard to have to pay student fees even when your tuition is covered, as much as that sucks. But the research expenses are a different story. I hope you are able to find some support. 

I don't think it's particularly harsh. Grading in graduate school is very different - As are expected, Bs are okay but often a sign that your work isn't up to the expected standard, and very often Cs are a sign that you failed the class. A 2.98 indicates mostly Bs with some Cs, which is not an acceptable level of achievement in a PhD program.

Did you go to disability services? You have to actually go to disability services and disclose your disability in order to get the help. It's not illegal for universities to not accommodate you if they don't even know you have the disability; it's only illegal for them to refuse to accommodate you once they know about it.
 
With that said, I agree that you should try the appeal, particularly if your program director is on board - but I also think that your approach needs to be a bit different than evidenced here in your posts. It shouldn't be about how a 3.0 is an arbitrary dividing line (it isn't - it's pretty standard) or how you shouldn't be held accountable for MBA-level classes (why shouldn't you?) The focus should be on your personal health issues that made it difficult for you to achieve to your full potential, but those health issues are handled/you are seeking support with disability services to get accommodations for them, so now you can perform to expected levels.
 
Good luck.

About your dog: I think that depends entirely on you and your program. I am in a social science program where the majority of my analysis and writing can be done from home, and I prefer to work from home or from a library (as opposed to my cube in the windowless cube farm). When I was taking classes I was generally there from 9-6 or so, but now that my coursework is finished I am rarely at the school itself. I go for meetings, seminars, interesting kinds of things and I do most of my work remotely. My time is verrry flexible, and if my building didn't prohibit it I would get a dog in a heartbeat. Another thing to keep in mind: a dog can be a great comfort when you're all stressed out over graduate school.

Advice?

Age:
-Don't feel like you have nothing to offer just because you are younger. I was 22 when I started graduate school. You got accepted to the program for a reason, and chances are you are just as equipped as any older students are to successfully complete the program, just in a different way.

-Your older classmates may be just as terrified as you. Talk to them. You have a lot in common. You are, after all, in the same place.

-You will feel like an imposter, like you don't belong, or like you are constantly behind. Or all three. It's normal. It will pass. (Well, sort of.) People of all ages go through this.

Adviser related:
-If you are lucky enough to get both research interest fit and personality fit perfect, congratulations! But sometimes, personality fit is more important than research interest fit as long as the research isn't too different. A great adviser is interested in your career development, likes you as a person, advocates for you, and wants to hear your ideas. Even if his or her research is quite different from yours, they may give you the autonomy to work on your own projects and just supervise you. A bad personality fit will drive you nuts, even if you love his or her research. Consider that when evaluating your adviser fit. (This will vary by field: research fit may be less important in the humanities, more important in the natural and physical sciences. Social sciences are somewhere in-between.)

-Don't be afraid to be straight up blunt with your adviser when it comes to asking about your progress. Ask if you are where you should be both academic program wise and getting-a-job-after-this-mess-wise.

-Be proactive. Advisers love when you draw up an agenda for your one-on-one meetings, come with talking points and progress to share, have concrete questions to ask, and have overall shown that you have been thoughtful and taken control of your own program. Of course, this won't immediately come easily to you, but in time you will work up to it. Every semester I type up my semester goals, and at the beginning of the year I type up annual goals. I show them to my adviser and we talk about whether they are too ambitious, or whether I need to revise them, and how I can meet them.

-Don't expect your adviser to actually know what courses you have to take to graduate. They will know about comprehensive exams and the dissertation, but a lot of professors don't really keep up with the course requirements, especially if their program is in flux. Get you a student handbook, and find out what you need to take. Map it out in a grid, and check off things when you finish them. Show this to your adviser every semester. You may have to explain how such and such class fills a requirement.

-Nobody loves you as much as you, except your mother. Keep this in mind as you take in advice from all sources, including your adviser. Your adviser is there to guide you, but that doesn't mean you have to do everything he says.

Studying:
-You will have to read more than you ever did before, in less time than you ever have before, and you will be expected to retain more than you ever have before. The way that you studied in undergrad may need some tweaking. Be prepared for this.

-Corollary: you may find that your methods change with age or interests or time. I preferred to study alone in college, but in grad school, I prefer to study in groups. It keeps me on task and the socialization keeps me motivated. You may find that you shift from being a more auditory learner to a visual learner or whatever.

-You will feel behind at first. This is normal.

-At some point you will realize that your professors don't actually expect you to read everything they assign you. This, of course, will vary by program, but there will be at least one class where the reading is actually impossible to do in one week. The point is to read enough that you know the major themes and can talk intelligently about them, and then pick some of the readings to really dig into and think more deeply about.

-For most programs, don't worry so much about grades. If you stay on top of your work and do what you're supposed to, you will probably get an A. How much grades matter varies from program to program. In some programs, a B is a signal that you are not up to par, and more than a few Bs will warrant a discussion with your adviser or the DGS. My program isn't like that - A, B, it's all meaningless. My adviser doesn't even know what my grades are. But at almost all programs, a C means you need to retake the course, and two Cs means you have to convince the DGS not to kick you out.

Extracurricular activity: What's that? No, seriously:
-A lot of your time will be unstructured. You will have coursework, but most grad classes meet once a week for two hours and you may have three classes. You may have meetings with your adviser every so often and some seminars or things to catch (like we have grand rounds and colloquia that are required), but a lot of time will be unstructured. However, since you have so much more work than you had in undergrad, you actually will have less free time than you had in undergrad. This may initially cause you great anxiety. It did for me. Some people love unstructured time, though. (I don't.)

-Because of this, you'll have to be planful about your non-grad school related stuff.

-TAKE TIME OFF. DO it. It's important for your mental health. However you do it doesn't matter. Some people work it like a 9-5 job. Some people take a day off per week (me) and maybe a few hours spread across the week. Some people work half days 7 days a week. However you do it, there needs to be a time when you say "f this, I'm going to the movies."

-Find your happy place, something that keeps you the you you were when you came in. I love working out. It gives me energy and I feel good. I stay healthy. I also love reading fiction, so sometimes I just curl up with a good book, work be damned. You have to give yourself permission to not think about work, at least for a couple of hours a week. You may also discover new hobbies! (I never worked out before I came to graduate school.)

-Your work will creep into all aspects of your life, if you let it. This is why I hate unstructured time. You will feel guilty for not doing something, because in graduate school, there is ALWAYS something you can do. ALWAYS. But since there will always be more work, there's no harm in putting it aside for tomorrow, as long as you don't have a deadline.

-You may need to reach outside of your cohort for a social life. None of my close friends are in my doctoral cohort. I've met master's students in my program, master's students in other programs, and I know a few non-graduate students I hang out with, too. Go to graduate student mixers. (If your university doesn't have any, organize some, if you like planning parties.) Join a student group that doesn't take up too much time. I had a doctoral acquaintance who kinda laughed at me because I joined some student groups other than the doctoral student one, and I was usually the only doctoral student in those groups, but I met some close friends (and future job contacts) and had a good time.

-DO NOT FEEL GUILTY FOR WANTING A LIFE OUTSIDE OF GRADUATE SCHOOL. This is paramount. This is important. You are a well-rounded, complex, multifaceted human being. NEVER feel bad for this. Everybody wants some kind of life outside of work. Yes, you may loooove your field, but that doesn't mean you want to do it all day long. Some other doctoral students, and perhaps professors, may make you feel bad about this. Don't let them. Just smile and nod. Then disappear when you need to.

Career:
-This is job preparation. Remember that from Day One. Always be looking for ways to enhance your skills. Read job ads and find out what's hot in your field, what's necessary, what's in demand. For example, in my field statistics and methods are a hot commodity, and they're not a passing fad. I happen to really like statistics and methods, so I have pursued that as a concentration of mine.

-Don't be afraid to take on volunteer work and part-time gigs that will give you skills that will be useful both inside academia and out, as long as it's not against your contract. Your adviser may be against it, but he doesn't have to know as long as it doesn't interfere with your work.

-If you want to work outside of academia - if you are even *considering* the possibility - please please definitely do the above. Even if you aren't considering it, consider the possibility that you won't get a tenure-track job out the box and that you may need to support yourself doing something else for a while. You will have to prove to employers that you have developed usable, useful skills and this is one of the easiest ways to do it. But don't overdo it - get the degree done.

-For more academic related ones - always look for opportunities to present and publish. Presentations look good on your CV. Publications look better. When you write seminar papers, wonder if you can publish them with some revision. Write your seminar papers on what you maybe think you may want to do your dissertation on. Even if you look at them three years later and think "these suck," you can at least glean some useful references and pieces from them. Discuss publication with your adviser early and often, and if you have the time and desire, seek out publication options with other professors and researchers. But if you commit to a project, COMMIT. You don't want to leave a bad impression.

-If you can afford it, occasionally go to conferences even if you aren't presenting. You can network, and you can hear some interesting talks, and you may think about new directions for your own research. You can also meet people who may tell you about jobs, money, opportunities, etc.

-Always try to get someone else to pay for conference travel before you come out of pocket. Including your adviser. Do not be shy about asking if he or she can pay. If he can't, he'll just say no. Usually the department has a travel fund for students, but often it's only if you are presenting.

-If you are interested in academia, you should get some teaching experience. There are two traditional ways to do this: TAing a course, and teaching as a sole instructor. If you can help it, I wouldn't recommend doing a sole instructor position until you are finished with coursework. Teaching takes a LOT of time to do right. You should definitely TA at least one course, and probably a few different ones. But don't overdo it, if you can help it, because again, it takes a LOT of time. More than you expect at the outset. If you are in the humanities, I think sole instructor positions are very important for nabbing jobs so when you are in the exam/ABD phase, you may want to try at least one. If your own university has none, look at adjuncting for nearby colleges, including community colleges. (I would wager that the majority of natural science/physical science students, and most social science students, have never sole taught a class before they get an assistant professor job. At least, it's not that common n my field, which straddles the social and natural sciences.)

-Always look for money. Money is awesome. If you can fund yourself you can do what you want, within reason. Your university will be thrilled, your adviser will be happy, and you can put it on your CV. It's win-win-win! Don't put yourself out of the running before anyone else has a chance to. Apply even if you think you won't get it or the odds are against you (they always are), as long as you are eligible. Apply often. Apply even if it's only $500. (That's conference travel!) Money begets money. The more awards you get, the more awards you will get. They will get bigger over time. If you are in the sciences and social sciences, you should get practice writing at least one grant. You don't have to write the whole thing, but at least get in on the process so that you can see how it's done. Grant-writing is very valuable both in and outside of graduate school.

-Revise your CV every so often. Then look and decide what you want to add to it. Then go get that thing, so you can add it.

-The career office at big universities is often not just for undergrads. I was surprised to learn that my career center offers help on CV organization and the academic job search, as well as alternative/non-academic career searches for doctoral students. In fact, there are two people whose sole purpose it is to help PhD students find nonacademic careers, and they both have PhDs. This will vary by university - some universities will have very little for grad students. Find out before you write the office off.

-It's never too early to go to seminars/workshops like "the academic job search inside and out", "creating the perfect CV," "getting the job," etc. NEVER. Often the leader will share tips that are more aimed towards early graduate students, or tidbits that are kind of too late for more advanced students to take care of. This will also help you keep a pulse on what's hot in your field. It'll help you know what lines you need to add to your CV. And they're interesting.

Other:

-Decide ahead of time what you are NOT willing to sacrifice on the altar of academia. Then stick to it.
I'm serious. If you decide that you do NOT want to sacrifice your relationship, don't. If it's your geographical mobility, don't. I mean, be realistic, and realize that there will always be trade-offs. But you have to think about what's important to you for your quality of life, and realize that there is always more to you than graduate school.

-If you don't want to be a professor, do not feel guilty about this. At all. Zero. However, you will have to do things differently than most doctoral students. Your adviser will probably never have worked outside of the academy (although this may vary depending on the field) so he may or may not be able to help you. But you have a special mission to seek out the kinds of experiences that will help you find a non-academic job. Test the waters with your adviser before you tell him this. My adviser was quite amenable to it, but that's because I told him that my goal was to still do research and policy work in my field just not at a university, AND because it's quite common in my field for doctoral students to do non-academic work. If you're in a field where it's not common (or where your professors refuse to believe it's common, or it's not supposed to be common)…well, you may be a little more on your own.

-Every so often, you will need to reflect on the reasons you came to graduate school. Sometimes, just sit and think quietly. Why are you doing this to yourself? Do you love your field? Do you need this degree to do what you want to do? Usually the answer is yes and yes, and usually you'll keep on trucking. But sometimes when the chips are down you will need to reevaluate why you put yourself through this in the first place.

-To my great dismay, depression is quite common in doctoral students. Graduate work can be isolating and stressful. Luckily your health insurance usually includes counseling sessions. TAKE THEM if you need them. Do not be ashamed. You may be surprised with who else is getting them. (I found out that everyone in my cohort, including me, was getting mental health counseling at a certain point.) Exercise can help, as can taking that mental health day once a week and just chilling. Don't be surprised if you get the blues…

-…but be self-aware and able to recognize when the depression is clouding your ability to function. Doctoral programs have a 50% attrition rate, and this is rarely because that 50% is less intelligent than, less motivated than, less driven than, or less ambitious than the other 50% that stays. Often they realize that they are ridiculously unhappy in the field, or that they don't need the degree anymore, or that they'd rather focus on other things in life, or their interests have changed. All of this is okay!

-You will, at some point, be like "eff this, I'm leaving." I think almost every doctoral student has thought about dropping out and just kicking this all to the curb. You need to listen to yourself, and find out whether it is idle thought (nothing to worry about, very normal) or whether you are truly unhappy to the point that you need to leave. Counseling can help you figure this out.

-Don't be afraid to take a semester or a year off if you need to. That's what leaves of absence are for.

Lastly, and positively…

…graduate school is great! Seriously, when else will you ever have the time to study what you want for hours on end, talk to just as interested others about it, and live in an intellectual community of scholars and intellectuals? And occasionally wake up at 11 am and go to the bank at 2 pm? Sometimes you will want to pull out all of your hair but most of the time, you will feel fulfilled and wonderfully encouraged and edified. So enjoy this time!

About your dog: I think that depends entirely on you and your program. I am in a social science program where the majority of my analysis and writing can be done from home, and I prefer to work from home or from a library (as opposed to my cube in the windowless cube farm). When I was taking classes I was generally there from 9-6 or so, but now that my coursework is finished I am rarely at the school itself. I go for meetings, seminars, interesting kinds of things and I do most of my work remotely. My time is verrry flexible, and if my building didn't prohibit it I would get a dog in a heartbeat.

Discuss publication with your adviser early and often, and if you have the time and desire, seek out publication options with other professors and researchers. But if you commit to a project, COMMIT. You don't want to leave a bad impression.

-If you can afford it, occasionally go to conferences even if you aren't presenting. You can network, and you can hear some interesting talks, and you may think about new directions for your own research. You can also meet people who may tell you about jobs, money, opportunities, etc.

-Always try to get someone else to pay for conference travel before you come out of pocket. Including your adviser. Do not be shy about asking if he or she can pay. If he can't, he'll just say no. Usually the department has a travel fund for students, but often it's only if you are presenting.

-If you are interested in academia, you should get some teaching experience. There are two traditional ways to do this: TAing a course, and teaching as a sole instructor. If you can help it, I wouldn't recommend doing a sole instructor position until you are finished with coursework. Teaching takes a LOT of time to do right. You should definitely TA at least one course, and probably a few different ones. But don't overdo it, if you can help it, because again, it takes a LOT of time. More than you expect at the outset. If you are in the humanities, I think sole instructor positions are very important for nabbing jobs so when you are in the exam/ABD phase, you may want to try at least one. If your own university has none, look at adjuncting for nearby colleges, including community colleges. (I would wager that the majority of natural science/physical science students, and most social science students, have never sole taught a class before they get an assistant professor job. At least, it's not that common n my field, which straddles the social and natural sciences.)

-Always look for money. Money is awesome. If you can fund yourself you can do what you want, within reason. Your university will be thrilled, your adviser will be happy, and you can put it on your CV. It's win-win-win! Don't put yourself out of the running before anyone else has a chance to. Apply even if you think you won't get it or the odds are against you (they always are), as long as you are eligible. Apply often. Apply even if it's only $500. (That's conference travel!) Money begets money. The more awards you get, the more awards you will get. They will get bigger over time. If you are in the sciences and social sciences, you should get practice writing at least one grant. You don't have to write the whole thing, but at least get in on the process so that you can see how it's done. Grant-writing is very valuable both in and outside of graduate school.

-Revise your CV every so often. Then look and decide what you want to add to it. Then go get that thing, so you can add it.

-The career office at big universities is often not just for undergrads. I was surprised to learn that my career center offers help on CV organization and the academic job search, as well as alternative/non-academic career searches for doctoral students. In fact, there are two people whose sole purpose it is to help PhD students find nonacademic careers, and they both have PhDs. This will vary by university - some universities will have very little for grad students. Find out before you write the office off.

-It's never too early to go to seminars/workshops like "the academic job search inside and out", "creating the perfect CV," "getting the job," etc. NEVER. Often the leader will share tips that are more aimed towards early graduate students, or tidbits that are kind of too late for more advanced students to take care of. This will also help you keep a pulse on what's hot in your field. It'll help you know what lines you need to add to your CV. And they're interesting.

Other:

-Decide ahead of time what you are NOT willing to sacrifice on the altar of academia. Then stick to it.
I'm serious. If you decide that you do NOT want to sacrifice your relationship, don't. If it's your geographical mobility, don't. I mean, be realistic, and realize that there will always be trade-offs. But you have to think about what's important to you for your quality of life, and realize that there is always more to you than graduate school.

-If you don't want to be a professor, do not feel guilty about this. At all. Zero. However, you will have to do things differently than most doctoral students. Your adviser will probably never have worked outside of the academy (although this may vary depending on the field) so he may or may not be able to help you. But you have a special mission to seek out the kinds of experiences that will help you find a non-academic job. Test the waters with your adviser before you tell him this. My adviser was quite amenable to it, but that's because I told him that my goal was to still do research and policy work in my field just not at a university, AND because it's quite common in my field for doctoral students to do non-academic work. If you're in a field where it's not common (or where your professors refuse to believe it's common, or it's not supposed to be common)…well, you may be a little more on your own.

-Every so often, you will need to reflect on the reasons you came to graduate school. Sometimes, just sit and think quietly. Why are you doing this to yourself? Do you love your field? Do you need this degree to do what you want to do? Usually the answer is yes and yes, and usually you'll keep on trucking. But sometimes when the chips are down you will need to reevaluate why you put yourself through this in the first place.

-To my great dismay, depression is quite common in doctoral students. Graduate work can be isolating and stressful. Luckily your health insurance usually includes counseling sessions. TAKE THEM if you need them. Do not be ashamed. You may be surprised with who else is getting them. (I found out that everyone in my cohort, including me, was getting mental health counseling at a certain point.) Exercise can help, as can taking that mental health day once a week and just chilling. Don't be surprised if you get the blues…

-…but be self-aware and able to recognize when the depression is clouding your ability to function. Doctoral programs have a 50% attrition rate, and this is rarely because that 50% is less intelligent than, less motivated than, less driven than, or less ambitious than the other 50% that stays. Often they realize that they are ridiculously unhappy in the field, or that they don't need the degree anymore, or that they'd rather focus on other things in life, or their interests have changed. All of this is okay!

-You will, at some point, be like "eff this, I'm leaving." I think almost every doctoral student has thought about dropping out and just kicking this all to the curb. You need to listen to yourself, and find out whether it is idle thought (nothing to worry about, very normal) or whether you are truly unhappy to the point that you need to leave. Counseling can help you figure this out.

-Don't be afraid to take a semester or a year off if you need to. That's what leaves of absence are for.

Lastly, and positively…

…graduate school is great! Seriously, when else will you ever have the time to study what you want for hours on end, talk to just as interested others about it, and live in an intellectual community of scholars and intellectuals? And occasionally wake up at 11 am and go to the bank at 2 pm? Sometimes you will want to pull out all of your hair but most of the time, you will feel fulfilled and wonderfully encouraged and edified. So enjoy this time!

It's actually pretty hard to plan this out in advance, as you often have to test out any system that you plan and sometimes the system you select ahead of time doesn't really work for you. Learning how to use Zotero and OneNote ahead of time are good tasks so you're not wasting brain power doing that mid-stream. You may want to check out other reference managers to make sure Zotero is the one you want to go with (Mendeley is a common favorite). I'm not sure that LaTeX is necessary, although it depends on your work style and also what field you're in. (I have a PhD in psychology and did not find it useful.)
I'll actually go out on a limb and say that you might want to spend this free time just relaxing and doing some fun stuff. Your time is about to become greatly constrained, and graduate school can be a very stressful experience. When you look back, I'm willing to bet you'll be more likely to regret not enjoying yourself in your last months before graduate school than you are to regret picking up some small skill that can be easily picked up in graduate school.

One of the secrets of academia I found out around my third year is that very few people actually read journal articles for the "fine details". Most researchers quickly scan articles - they read the abstract, and then if they decide to read further, they skim the methods and results with a quick glance at the discussion. The volume of research papers that come out every month in an area is just too great to devote time to close reading of each article.
When I studied for comps I didn't set reading goals. Instead, I set goals of being able to answer certain questions that would mirror what I'd be asked on the exams. For my written exams, there were past exams that I could access with examples of questions that had been asked going back 10 years or so, so I spent some time looking at those questions, then determining what I needed to know to answer the question. Early in comps study, I worked backwards from there and worked through my reading list in a rough priortization order - starting off by reading the material that I most needed to answer the questions, but had new concepts that I didn't already know from prior classes/readings. Then I went and filled in the gaps, and lastly I read the sort of supplemental/extraneous material that really just fleshed out the answer. All along, I practiced answering questions by outlining and then writing full responses. You want the truth? I think I read maybe 10-15% of what was on the 12-page reading list for my program (which including full-length books!!), and a lot of that I skimmed really well.
Honestly, you don't really need fine details for comps (well, most comps, in my experience). You should be able to cite big/seminal works in the field, but nobody expects you to remember all the little details of the results and design and xyz for your comps papers.
