When you first start writing-and I think it's true for a lot of beginning writers-you're scared to death that if you don't get that sentence right that minute it's never going to show up again. And it isn't. But it doesn't matter-another one will, and it'll probably be better. And I don't mind writing badly for a couple of days because I know I can fix it-and fix it again and again and again, and it will be better.
