I have never thought of myself as a good writer. Anyone who wants reassurance of that should read one of my first drafts. But I’m one of the world’s great rewriters.
I find that three or four readings are required to comb out the cliches, line up pronouns with their antecedents, and insure agreement in number between subject and verbs… I can never recall anything of mine that’s ever been printed in less than three drafts.
You write that first draft really to see how it’s going to come out.
