If the world were merely seductive, that would be easy. If it were merely challenging, that would be no problem. But I arise in the morning torn between a desire to improve (or save) the world and a desire to enjoy (or savor) the world. This makes it hard to plan the day.
Writer's block is what you get if you're too full of yourself and trying to be García Márquez. You sit and stare at the wall and nothing happens for you. It's like imagining you're a tree and trying to sprout leaves. Once you come to your senses and accept who you are, then there's no problem. I'm not García Márquez. I'm a late-middle-aged midlist fair-to-middling writer with a comfortable midriff, and it gives me quite a bit of pleasure.
