I'll answer 'cause I have my BA already
1) Went to college, got my BA in Environmental Policy
2) I'm happy that I did it, 'cause now I have a lot of experience in the field I want to go into, and I got to meet a lot of great people and expand my personal horizons. I truly matured from the experience.
3) Oddly enough, I was making significantly more with my HS diploma than with my BA, but I blame that more on the economy than anything. I don't regret anything though...
College was a tooth and nail fight for me... See, I didn't exactly have the money for another year of school, so I graduated in three years (When I was 20), which killed me... I was incredibly burnt out in the end... and in retrospect, all I really would have done differently would have been that I would have taken a year off...
But yeah... I'm glad I have my BA. It's because that when I decide that I'm ready for the real world, I can jump in with the minimum qualifications for a good job...
a BA doesn't exactly mean you're an expert in that field... a BA means you can jump through a lot of hoops, and you have a specific interest in a certain subject... Thus, a lot of employers look for a BA as a sign that someone can do work effectively under a deadline, and has basic real-world professional skills.
IMO, get your BA man, no matter what. BUT if you're feeling burnt out, I'd take a year off... better that you pace yourself and do it right than burn yourself and never finish
