When I was 14, I was doing undergraduate research and playing video games. You don't really have to pick.

I started college part time when I was 12, full time at 13, and it was basically fine. There wasn't really much for bumps in the road, and everyone just treated me as a peer (although I got a lot of the obvious questions). It's really just not that big of a deal.
