But once you try your hand at it, you soon find that it isnāt as peaceful a job as it seems. The whole processāsitting 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 trackārequires far more energy, over a long period, than most people ever imagine. You might not move your body around, but thereās 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.
