I am 35 and have a ten year old. Finishing up a masters degree right now, and it has been a struggle. It's been very difficult to make sure I am there to help with homework, read books with him, and just even sometimes even being available with the amount of coursework to do.
I came to academia late. Did college for a year right out of high school, almost failed out because I didn't want to be there. Restarted school nine years later, did an AA, then the BA, now the masters and applying for the PhD. It is very different to be in class with 24 year olds, and to be teaching people who were born my freshman year in high school....
