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.

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 think I can recognize when a piece is at a state of completion. I always say to my wife, "Oh yeah, it's roughly finished." I've got it there. And then there's that whole other phase of moving on to properly amp up the sentences and sometimes to move stuff around as well.

Nine times out of 10, the most charming thing to say in any given situation will be the exact opposite of what one really feels.

One of the reasons so many nonfiction books are so boring is because what they've done, very diligently, is fulfill the terms of their proposals. They've written up their proposal, long-form, and often what this does is then set up a sort of serial deal, where the whole book can essentially be reduced back to the size of the original proposal!

Nicholson Baker talks about the way in which the most successful nonfiction books are those that can be boiled down into an argument so that everybody can wade in with an opinion without having to undergo the inconvenience of having to read the book itself. The more you can condense it, the better.

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.
