I first went to college at 35. Was going to do the teaching program and be a teacher.
Went full time to the local community college (while running my business.) Got my AA degree (2 yrs. 3.9 gpa) I moved on to a 4 year school, but biz became too busy, and I hated the 4 year school I had to transfer to anyway (because they catered to kids... as a new student, I actually had to attend a seminar on the dangers of drugs, drinking, and sex and such. They also told us things like "now that you're out of your parent's house, you should do your laundry every week". They didn't care that I was 37, was married, and owned a home with a washing machine...)
I *hate* red tape like this, and figured the entire school structure is full of mindless non-decision making drones who can't say "yea, you don't need to attend" for fear of the boss yelling at them. Besides, biz was good, so I left (I'd have gotten fired as a teacher anyway the minute I explained to little Johnny's mother that little Johnny is a fucking moron, and that's why he's failing.)
But I'm really happy I did the two years. Made me a better person.
