I got a BA in Computer Science (with mediocre grades) in college because I wasn't mature enough to apply myself in the difficult mathematics courses. I'm not sure if I can manage to do interesting/valuable things without going back to school. My entire career has consisted of making and maintaining more or less the same applications for 10 years. I know I could just self-teach it all, but I do much better with a peer group and a little structure. Sad, but I don't see a way out of it.
