Right now I’m aiming at increasing the distance I run, so speed is less of an issue. As long as I can run a certain distance, that’s all I care about. Sometimes I run fast when I feel like it, but if I increase the pace I shorten the amount of time I run, the point being to let the exhilaration I feel at the end of each run carry over to the next day. This is the same sort of tack I find necessary when writing a novel. I stop every day right at the point where I feel I can write more. Do that, and the next day’s work goes surprisingly smoothly. I think Ernest Hemingway did something like that. To keep on going, you have to keep up the rhythm. This is the important thing for long-term projects. Once you set the pace, the rest will follow. The problem is getting the flywheel to spin at a set speed—and to get to that point takes as much concentration and effort as you can manage.

In every interview I’m asked what’s the most important quality a novelist has to have. It’s pretty obvious: talent. No matter how much enthusiasm and effort you put into writing, if you totally lack literary talent you can forget about being a novelist. This is more of a prerequisite than a necessary quality. If you don’t have any fuel, even the best car won’t run.

If I’m asked what the next most important quality is for a novelist, that’s easy too: focus—the ability to concentrate all your limited talents on whatever’s critical at the moment. Without that you can’t accomplish anything of value, while, if you can focus effectively, you’ll be able to compensate for an erratic talent or even a shortage of it.

But once you try your hand at it, you soon find that it isn’t as peaceful a job as it seems. The whole process—sitting at your desk, focusing your mind like a laser beam, imagining something out of a blank horizon, creating a story, selecting the right words, one by one, keeping the whole flow of the story on track—requires far more energy, over a long period, than most people ever imagine. You might not move your body around, but there’s grueling, dynamic labor going on inside you. Everybody uses their mind when they think. But a writer puts on an outfit called narrative and thinks with his entire being; and for the novelist that process requires putting into play all your physical reserve, often to the point of overexertion.

If possible, I’d like to avoid that kind of literary burnout. My idea of literature is something more spontaneous, more cohesive, something with a kind of natural, positive vitality. For me, writing a novel is like climbing a steep mountain, struggling up the face of the cliff, reaching the summit after a long and arduous ordeal. You overcome your limitations, or you don’t, one or the other. I always keep that inner image with me as I write.
