Although I'm not a wise sage quite yet, I am finishing up my final semester of college and so have been reflecting on what college has meant to me over the past 4 years.
I started flying when I was 16, while in high school, then went to college at Arizona State (far from home), then quit flying to concentrate on studies.
Now that I'm back in the flying game, or will be soon, I've realized how important college is. I've realized I can learn things much more quickly and efficiently, teach concepts better, have better people skills, and can write much more professionally. All these things will give you a huge edge in life over people without a degree...Also, no matter how mature one can be, college takes it to a whole different level. One can be mature without a college degree, but it takes a college degree to be professional. This is of course, my opinion.
You should come to Arizona State! I had a great time. It's sunny everyday, beautiful women parade the campus, a number of great professors work there, and they even have a flight program at the East Campus. From what I've heard, people really enjoy it.
Hope you do well regardless, just 'put in the time' and you'll feel the satisfaction in the end!
