To write is to practice, with particular intensity and attentiveness, the art of reading. You write in order to read what you've written and see if it's O.K. and, since of course it never is, to rewrite it once, twice, as many times as it takes to get it to be something you can bear to reread. You are your own first, maybe severest, reader. "To write is to sit in judgment on oneself," Ibsen inscribed on the flyleaf of one of his books. Hard to imagine writing without rereading.
