The most important thing is to find something you love, and for which you have some aptitude. Don't make the same mistake that some college students do, in that they choose a career path for $$$ only. Even if a job pays big bucks, you'll be miserable if you don't love it. And, if you try to study something you don't really understand, you'll be stressed out trying to pass the course.
A co-worker told me, "Get into computers: you'll make a lot of money." That's actually true...if I had any aptitude for computers, and if I provided anything valuable for the marketplace. There are some things I'd like to do that would require computer skills, so I figured I'd take a shot at it. (I didn't go to any school, but tried to learn it on my own.)
As it turned out, going to school for computer skills would have been a waste of time and money. I tried to learn how to write computer programming code, and tried to understand the basics of the technology. But I found the subject boring, and it just didn't take! If I had tried to go to school for that, I would have been totally stressed out. Even if I could learn anything, and even if I could have gotten a job in the computer industry, I would not have been happy. I just don't enjoy that kind of work, and no amount of money could have persuaded me otherwise.
If I had to sit in front of a monitor for hours on end, I would much rather write a novel or a history book. Writing and research are the only things I can do, anyway. At least I enjoy it.
