Like most writers I spend a lot of my time sort of thinking, "It's such agony, I can't do it."

One's happiness is very largely a question of state of mind rather than the world you are looking at.

I want to stress, this is the experience-growing up in a working-class family-that defined me and continues to define me. It's the core of my being. And it explains, incidentally, a good deal about my love of America.

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 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.

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.
