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.

If the regular length of a shot is increased, one becomes bored, but if you keep on making it longer, a new quality emerges, a special intensity of attention.' At first there can be a friction between our expectations of time and Tarkovsky-time and this friction is increasing in the twenty-first century as we move further and further away from Tarkovsky-time towards moron-time in which nothing can last—and no one can concentrate on anything—for longer than about two seconds.

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.

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.

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.

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.
