I guess that as life is speeded up and our capacity for concentration is being nibbled away at by all the obvious things, that leads us actually to be more susceptible to boredom.

It's this thing that's going on all the time - aging. Paul Auster quotes the poet George Opren on growing old: "What a strange thing to happen to a little boy." Which I think is so profound.

Have regrets. They are fuel. On the page they flare into desire.

Beware of clichés. Not just the ­clichés that Martin Amis is at war with. There are clichés of response as well as expression. There are clichés of observation and of thought - even of conception. Many novels, even quite a few adequately written ones, are ­clichés of form which conform to clichés of expectation.

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.

Quite often, ambition operates on a level of irritation. Not even jealousy, just irritation.

What I'm really interested in, as a reader and as a writer, is the idea of the nonfiction book that is not defined by its content, by its "about"-ness. Where you read it irrespective of whether you're interested in the subject.
