A guitar for me is pretty much strictly in the context of writing songs for my band, coming up with ideas with my band, and then being able to perform those songs as best as I can on stage - that's what the guitar for me has always been.
I mean, first, almost all writers these days teach because they don't make enough money publishing to live on, to support themselves - people like Tobias Wolff, Anne Beattie, Amy Hempel, Stuart Dybek; a lot of short story writers, for one thing.
The reason I never give up hope is because everything is so basically hopeless.
