I did a degree, even though while I was doing it, I was running my own business, and knew I'd never work for anyone.
The content was actually sorta useful (it was a hardcore computer degree), but the main thing I took from it was I finished it, and got a decent grade,despite it having a very high dropout rate.
I'd probably be richer right now if I hadn't gone to college, but I'm still glad I did it. I think I'd probably feel I'd missed out if I hadn't. (I was 24 when I graduated, as I worked before going).
Also, the way I feel right now, in my 40s I may well go back and do PhD in a psychology-related field. Purely for my own intellectual satisfaction. I'll be financially independent by then, so I want to do academic shit for fun. That would be a lot tougher if I didn't have my Bachelor's.
But I didn't think I'd feel that way now, back when I was doing my degree.
So yeah, go finish it.
