No offense, but college is not for everyone.
That being said, if you have the desire to learn and the ability to get a degree, then by all means go. A few others have said the course of study is not as important as just getting the piece of paper. This is sad but true.
I have a degree in B.S. in exercise physiology and then went on to become a doctor. I love what I do, however it is not for everyone. One of my good friends dropped out of medicine after four years of college, four years of medical school and two years of residency training. Now he is writing and directing plays in NYC.
If you like working with your hands being a doctor is great, but so is being a plumber. (many of them make more than most docs

)
The hard part is finding something you love doing and then find a way to make money at it.
Sometimes college is not worth it. Yes, most college grads make more money than those without degrees, but is it worth the time, effort and expense to you. My career did not really start til I was in my early thirties, and I spent a few hundred grand on school. Also there was very little time for family and fun, until recently. If I had become a plumber, I would have had a career about ten to fifteen years sooner and I would have a lot more money in the bank.
I went to the twenty-third grade in school and now make a pretty good living. Currently, I enjoy what I do. However, I still don't know what I want to be when I grow up
Before you run off to get a degree or trade school (or circus... there are clown colleges) try to spend a lot of time with people who do the type of job you are looking into. Volunteer, spend time with, and ask a lot of questions about the fields you may be interested in.
Good Luck!
P.S. The most interesting people I know are in their forties and still don't know what they want to be when they grow up!
