Quite often, ambition operates on a level of irritation. Not even jealousy, just irritation.

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.

Mike Pence came out and said this was a courtesy call, then Donald Trump a few hours later went on Twitter, as is his wont, and essentially linked the call to Taiwan with a whole series of things he doesn't like about Chinese economic and foreign policies and implied that the U.S. views of the status of Taiwan are now up for negotiation, that he wants them to be part of a broader negotiation with China about a whole series of economic and foreign policy issues. So, we just don't really know what exactly they're planing to do with this.

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.

People say it's not what happens in your life that matters, it's what you think happened. But this qualification, obviously, did not go far enough. It was quite possible that the central event of your life could be something that didn't happen, or something you thought didn't happen. Otherwise there'd be no need for fiction, there'd only be memoirs and histories.

Whatever people may say about my books - and it always amazes me when people don't like them, but sometimes they don't - the epigraphs have always been top-drawer. I think having that at the outset protects me from a lot of potential problems.

I'd have no rituals, but I'm a person of compulsive habit. That's just some awful residue of a ritual. And one of the reasons for that is my living this life, which is otherwise so free of obligations. It's not at all unusual for anybody who's independently employed to crave a way of living whereby they create the structures without which their lives would otherwise start slopping around all over the place.
