I had no idea what to do starting college, then I dropped out. I went back later (long story) - ended up taking a logic course in philosophy program - aced it, and routed myself in to a philosophy degree. What the hell do you do with a philosophy degree? Get a programming job of course! (which is what I managed).
I was basically doing the drop out thing while I was in college. I would take 4 courses a semester, focus on whichever one piqued my interest, and then fail or drop out of the other 3. Wasted a lot of money.
