For so long I didn't have any kind of readership at all - I'd get published, but not read - the idea of writing for an audience is so anathema to me, it's never bothered me.

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.

The one thing that you can say about the new Cabinet Donald Trump is putting together. That seems to be one of the coherent themes. They're very, very skeptical about Iran.

I think I do have a sort of terrible propensity for boredom and for being bored, even though I am absolutely of the opinion that one shouldn't be bored and that there is no excuse for it and that it is a personal failing.

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.

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.

There's something about New York. You can get a nice feeling of belonging as a writer here. It's probably the best city on Earth like that. I miss the wisecracking of New York.
