I have advice for people who want to write. I don’t care whether they’re 5 or 500. There are three things that are important: First, if you want to write, you need to keep an honest, unpublishable journal that nobody reads, nobody but you. Where you just put down what you think about life, what you think about things, what you think is fair and what you think is unfair. And second, you need to read. You can’t be a writer if you’re not a reader. It’s the great writers who teach us how to write. The third thing is to write. Just write a little bit every day. Even if it’s for only half an hour — write, write, write.

My writing desk is covered in open novels. I read lines to swim in a certain sensibility, to strike a particular note, to encourage rigour when I’m too sentimental, to bring verbal ease when I’m syntactically upright. I think of reading like a balanced diet; if your sentences are baggy, too baroque, cut back on fatty Foster Wallace, say, and pick up Kafka, as roughage. If your aesthetic has become so refined it is stopping you from placing a single black mark on white paper, stop worrying so much about what Nabakov would say; pick up Dostoyevsky, patron saint of substance over style.
