I deal with writer’s block by lowering my expectations. I think the trouble starts when you sit down to write and imagine that you will achieve something magical and magnificent—and when you don’t, panic sets in. The solution is never to sit down and imagine that you will achieve something magical and magnificent. I write a little bit, almost every day, and if it results in two or three or (on a good day) four good paragraphs, I consider myself a lucky man. Never try to be the hare. All hail the tortoise.
