Hoboy...

I'd like to be able to learn, fluently, at least one other foreign language, and ideally three others; Mandarin, Spanish, and German. I've never had much of a way with foreign languages though, but I've always wanted a reason to really give it a try.

I'd love to be able to play a musical instrument; piano, ideally, but I wouldn't mind being able to play the guitar either.

And, like you Ghostwriter, I'd like to be able to edit videos well.
