I published so many books, which, for years, didn't get published here in America, at all - and which barely got any attention in England. So it wasn't going to take much to make me feel suddenly famous. So - yeah - after 20 years, I'm an overnight success.

In the '80s, the world I was living in wasn't this world of consumption. There wasn't that much to buy, really. Actually I'm still struck by that. There's not an awful lot of stuff I want. Somebody quotes Diogenes, who's walking around saying, "How many things there are in the marketplace of which Diogenes has no need." I always feel that. Except of course when you're living in Venice, California and you see all these lovely houses!

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.

All sorts of things can keep one awake. But as you get older - this is what the stroke thing really brought home to me - this thing that I never paid attention to: my brain. I've always been conscious that, of course, after a night of getting stoned, my head would feel foggy; if I got drunk the night before I'd be hungover. But that was the extent of my concern about my brain. And then with the stroke thing, it made me realize, "God! That's my main source of income." So it relates actually to your other question about growing old.

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.

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.

The only distinction I'd make is between film and telly, I guess. "Film," "movies," and "cinema" are all synonyms as far as I'm concerned; but telly is different. It's just a plodding we've-done-this-scene, we've-done-that-scene and it never becomes this new other thing.
