[William] Eggleston's photographs look like they were taken by a Martian who lost the ticket for his flight home and ended up working at a gun shop in a small town near Memphis. On the weekend he searches for the ticket - it must be somewhere - with a haphazard thoroughness that confounds established methods of investigation.

I would agree on the aging thing. Because, at a certain point, once you start noticing it, it is your subject. And I know young that people, when they get to 30, say, "Oh, I'm so old." But actually, around 50, you do become conscious of it.

In my 30s I used to go to the gym even though I hated it. The purpose of going to the gym was to postpone the day when I would stop going. That's what writing is to me: a way of postponing the day when I won't do it any more, the day when I will sink into a depression so profound it will be indistinguishable from perfect bliss.

Getting too much money too soon can be really bad. There's a balance to be kept - the right balance between new experience and a certain stability in one's life. I'm conscious of all these things in a way that, earlier on, I was only conscious of circumstantial stuff, like, money.

To be interested in something is to be involved in what is essentially a stressful relationship with that thing, to suffer anxiety on its behalf.

I think, about the distinction between fiction and nonfiction. Fiction is not really about anything: it is what it is. But nonfiction - and you see this particularly with something like the BBC Samuel Johnson Prize for Non-Fiction - nonfiction we define in relation to what it's about. So, Stalingrad by Antony Beevor. It's "about" Stalingrad. Or, here's a book by Claire Tomalin: it's "about" Charles Dickens.

The perfect life, the perfect lie, I realised after Christmas, is one which prevents you from doing that which you would ideally have done (painted, say, or written unpublishable poetry) but which, in fact, you have no wish to do. People need to feel that they have been thwarted by circumstances from pursuing the life which, had they led it, they would not have wanted; whereas the life they really want is precisely a compound of all those thwarting circumstances.
