It's usually a big kind of vent of frustration or anger or sadness that puts me in the right frame of mind to write. It's such a cliche to say that artists write when they're down, but it's true for me. It's a relief to get out what's eating away at my heart or my soul or my head.
I'd do pretty much anything to get back on stage. I'd like to develop a new musical. I nearly had a heart attack when I heard that they're developing John Waters' Cry-Baby because that is so amazing and super and wonderful and I wish that I could be involved. But it's not the right time and I understand that. But I hear things like that and I get that little tingle in my stomach.
The daily act of writing remains as demanding and maddening as it was before, and the pleasure you get from writing - rare but profound - remains at the true heart of the enterprise. On their best days, writers all over the world are winning Pulitzers, all alone in their studios, with no one watching.
