I work hard and I party hard. When I go to work, I know what I am doing and I do it to the best of my abilities. When I party, I take exactly the same rule book with me.
I've seen novels that have grown out of one story in a collection. But it hasn't occurred to me to take any of those stories and build on them. They seem very finished for me, so I don't feel like going back and dredging them up.
