Ask HN: What should I try to do while still in college? 18 years ago
Pick up skydiving!
I did during my military service (compulsory between sophomore and junior year at my engineering school in France), and there's nothing better for your ADHD. Seriously, it looks very ballsy from outside, but it actually would fit super well with your craving for learning and discovery - plus it will help solve the women issue, see comment #1 :-) And it's the best way to meet people as crazy as you are but completely outside of your usual circles (kind of saved my life when I moved to MA ;-).
