Let me suggest that perhaps the process of getting a degree is FUN?
The point of college is NOT to hone your flying skills. It's to hone life skills, if you don't mind the cliché. Granted, the academic side of the college experience may not be for everyone, but consider the other component of the experience. I'm in my senior year at a big int'l university, and the friends I've made alone have made the process worthwhile. This is in addition to other extra curricular stuff you can get involved with (sports, student government, etc etc) and of course, the party life, which one's ability to enjoy has an expiration date (I'm getting there now, I think...toooooooo much beer in the last 3.5 years!)
I resent those who say those who have gone to college don't have "life experience". Working and living from paycheck to paycheck (which I have also done) is not any different between working on papers/exams. You need to accomplish something in order to survive, thus requiring the same ability to muster mental tenacity. Finally, the vast vast majority of kids work during the summer, so the job part of "life experience" is also accomplished. Therefore, I'd argue that college grads have just as much "life experience", with perhaps even a bit more variation, compared to non college grads.
And for the record, I can afford to eat much better during the summer when I am a CFI than when I'm at school!
