Serve your Subject

The best advice came from my agent, when I was a year or so into my career. I was dithering about a future project, saying that there was a way to do it that would be accessible and commercial, and a way to do it that would be smart but unpopular. He said, “Just write as well as you can.” That advice has saved me years. I never again asked the question, of myself or anyone else. It’s the only way to work—don’t write to what you perceive as a market. Don’t write out of anyone’s need except your own. Don’t try to cater to an audience you think may not be keeping up with you—find the audience who will. I have amplified the advice in my mind: just serve your subject. Each book makes different and fierce demands. Each one uses up all you can do. Later you may be able to do more.”
