“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” (pgs 78-80).
