hello!
I need some help deciding what to do, or at least hearing from other people, so that I can better inform my own decision
I just received an offer to Brown Sociology PhD program.  The offer includes full scholarship for tuition, health care, and $2,700 per month stipend.
I currently work for the government in Hawaii.  I earn 90k, and work in budgeting/financial analysis.  It's not ideally what I thought I'd be doing, but it is living on a tropical island and earning good money.  But when it is all said and done, I do not like or enjoy my job much.  It is just not that fun.  I am often sad or miserable doing it.  I have interests in social sciences, and the best time of my life was when I was doing my masters degree in Development studies in London.  I love reading articles, writing papers, researching, thinking, etc.
I would LOVE to be a professor - but I am about to turn 29, and I don't know if I should just find other work that appeals to me more, or go into the PhD program.  I look for jobs often, but it is hard to find ones that sound appealing to me and still earn a decent wage.
My background is in Economics, and although I like Sociology and it sounds the most "fun" and critical, I don't know how the job prospects are.
With that said, I am sure a PhD from Brown will go far.  And I'm a hard worker and have very global interests in Sociology, which I feel like is the future of the field.  Also, I would take a lot of quantitative courses, and maybe get a MA in Economics while I'm there. 
If I do the PhD, I would love to get a professorship in Europe and relocate there permanently.  Don't know how possible that is?
Overall, I'd say I'm very confused.  And could definitely use any input anyone has!!
