"Yes, writing can be complicated, exhausting, isolating, abstracting, boring, dulling, briefly exhilarating; it can be made to be grueling and demoralizing. And occasionally it can produce rewards. But it's never as hard as, say, piloting an L-1011 into O'Hare on a snowy night in January or doing brain surgery when you have to stand up for ten hours straight, and once you start you can't just stop. If you're a writer, you can stop anywhere, any time, and no one will care or ever kow. Plus, the results might be better if you do."
--Richard Ford, "Goofing Off While the Muse Recharges," in Writers [on Writing]: Collected Essays from The New York Times
