Remember that Tom Petty song, The Waiting? The lyrics say it all: "You take it on faith/You take it to the heart/The waiting is the hardest part."
I can't be specific about what I'm waiting for. It's just not politic. But waiting is part of what you have to do as a writer, and it just fricking sucks. So much about being a writer sucks! It's really hard, man. Don't do it unless you can't help yourself.
