Everybody says college is way better. It's supposed to be less all about cliques and stuff, and you get to mostly just take classes in what you're interested in. I've been thinking about what I'd have to do to make myself good at tabletop game design. It's not exactly a traditional major, but if I could work together some pieces from math and some pieces from design and some pieces from creative writing I might be able to make it work.
Maybe you would take some classes on teaching? Like, you know what worked for you, but it might help to learn some other ways to teach people stuff in case they don't learn the same way you did.
