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.

Each of my book arrives at a form and a style that is appropriate to 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.

He [Thelonious Monk] played each note as though astonished by the previous one, as though every touch of his fingers on the keyboard was correcting an error and this touch in turn became an error to be corrected and so the tune never quite ended up the way it was meant to.

I always hope to come up with a style of writing that's appropriate to the material and I felt like this was. And then there's plenty of - I don't know if it's the right word but - lampooning, but it's always at my expense.

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.
