Like, millions.
Things I have repeatedly tried to teach myself but always abandon simply from lack of time: drawing, poetry, piano, French, math, programming, 3d modeling, web design, cooking. I tried to learn how to knit once, too, but I got teased pretty mercilessly.
I dabble in all sorts of things that I would love to spend more time on. And some things I wish I could learn but that I know I'd never be good at, like singing and dancing.
Beauty isn't everything. It's the only thing.
