The whole process [of writing novels]—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….
Most of what I know about writing I’ve learned through running every day.
These are practical, physical lessons. How much can I push myself? How much rest is appropriate—and how much is too much? How far can I take something and still keep it decent and consistent? When does it become narrow-minded and inflexible? How much should I be aware of the world outside, and how much should I focus on my inner world? To what extent should I be confident in my abilities, and when should I start doubting myself?
I know that if I hadn’t become a long-distance runner when I became a novelist, my work would have been vastly different.
