Agreed. Many of us that are children of the 80's are obviously and woefully self-bootstrapped into the compsci and compeng industry. It really shows, compared to a lot of kids who are up-and-coming stars who already have mastery in subjects I haven't even had time to diversify into.
This is a regret of my childhood. So much time, and if only I'd had a good mentor for programming or music I'd have moved much further forward by now (and probably missed the angry young man stage as well).
Startup idea: simple mentoring site that aims to connect mentors in any topic with students in any topic. Can be free or commercial, can be regional or local, it's expected that both the student and mentor will need to pass some sort of test to be accepted. Students and mentors are reviewed.
