Nice post. I'm like most writers, I worry about everything, to very little effect. I'm working on it, though, particularly in terms of promotion. I'm taking the attitude that, Hey, point me where to go, I'll show up with a smile and make the best of it, then go home. What happens during a book signing has a lot more to do with the fates than it has to do with me sitting at a little desk in a bookstore.
