The idea for each of the stories in this book came in a moment of belief and was written in a burst of faith, happiness, and optimism. Those positive feelings have their dark analogues, however, and the fear of failure is a long way from the worst of them. The worst - for me, at least - is the gnawing speculation that I may have already said everything that I have to say, and am now only listening to the steady quacking of my own voice because the silence when it stops is just too spooky.
