Decision making... part one

I'm thinking about university alot lately, trying to figure out if i want to spend 9 years in school to teach at a university level and write, do i need to? IS that what i want? Will I ever know what i want for a career? At todays prices a doctorate costs 60,000 just for tuition, not including books, living expenses, and so on...it's a rich man's game to say the least. I sometimes feel as though this is my station, and any attempt to be a class jumper, might be an excercise in futility.
