We tried make something much more holistic and simple. When you first start off trying to solve a problem, the first solutions you come up with are very complex, and most people stop there. But if you keep going, and live with the problem and peel more layers of the onion off, you can oftentimes arrive at some very elegant and simple solutions. Most people just don't put in the time or energy to get there.

All of the above is the answer to that. I mean, I edit what I wrote yesterday before starting writing again today, so that’s the first sort of layer of editing. Then, suppose I have a chapter, then I’ll edit it again and again. Every word I publish has been through 30 edits. My first draft I do with a pencil. I just write freehand with a pencil. I do that for quite a while, and then I write with a pen. I make a draft with a pen. And then I get onto the computer. For me, it would be really kind of crippling if I were to go straight onto a computer. I would just freeze up. I think there’s a lot to be said for trying to find ways of not freezing up, of being able to be loose.

I worked as an editor until I joined the New Yorker , and so I’m an extremely tough self-editor. I also love being edited. I love a hard edit. It’s a privilege to be edited hard.

First of all, you can correct mistakes much more easily. One sweep of the palette-knife 'lifts' the blood and tears of a morning from the canvas and enables a fresh start to be made; indeed the canvas is all the better for past impressions.

Have more than one idea on the go at any one time. If it’s a choice between writing a book and doing nothing I will always choose the latter. It’s only if I have an idea for two books that I choose one rather than the other. I ­always have to feel that I’m bunking off from something.

Don’t write in public places. In the early 1990s I went to live in Paris. The usual writerly reasons: back then, if you were caught writing in a pub in England, you could get your head kicked in, whereas in Paris, dans les cafés . . . Since then I’ve developed an aversion to writing in public. I now think it should be done only in private, like any other lavatorial activity.
