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.
I still enjoy acting. I love the moment in front of the camera, but it's all the other moments that I don't enjoy. The 'business' aspect of it, the gossip.
