Finish college. It may be a pain in the tail, but it's worth it. If you don't, you will find your career path blocked, or you just won't get hired or promoted - you won't even know. Doesn't matter what your major is - employers look for that degree.
I agree. As a 31 year old recent graduate I speak from experience. As much as you may or may not enjoy classes it only gets harder as the years pass to get that degree.

Ultimately, do what you enjoy. Good luck.
