My friends and I sometimes laugh at each other that there is so much maintenance of a body. I paid no attention when I was younger.

I think that sense of surprise, that you don't know where something is going, or what's going to happen, even as you write, that you're making it up as you go along - that's important to me. It's not a question of shock or surprise in a gimmicky way. It's that as you read, you become more deeply into something and into what happens, and become more involved and engaged, you're learning something or you're appreciating something or seeing something differently - that's what's surprising.

Nothing is a matter of age. It's really in the person because you can publish book after book after book and still want that golden apple. And maybe it's the reality principle that has hit me. I believe that a career is very different from writing. My career is a certain kind of career.

What I don't like about teaching is hearing myself say the same thing. I mean, you just want to sort of shoot yourself after a while. But you don't have a million different ways of thinking about what you have been thinking about for many years. And then there's the truism that you're only as good as your students. If they're not into what's going on, it doesn't matter who you are.

Jokes are great capsules of information. I think they should never be censored. They often are offensive - and we're offended by different things - but I believe deeply in what Freud wrote of their relationship to the unconscious, which is that jokes come to help us. We laugh so as to dispense with, or to express, some ambivalence or discomfort with the things around us. That's what laughing is: a release.

You know how some people are upwardly mobile? I'm sort of downwardly mobile in the publishing world, because of my sales figures and also because of the kind of books I write. Everything really counts on sales. I started out with a bigger press, my first few books. But I've always done some things with independent and small presses and small magazines and I always will.

I'm not just interested in the thoughts I have, but also in others' thoughts, and why not carry those forward? That's why American fiction can be so thin. All these fears, like not seeming to be original - I mean, hell, most stuff isn't. The question is whether you can articulate your thoughts for the moment in which you're living, which is a different time. Say them in a newer way. There are new events, and language changes - sensibilities change. We are writing in and of the time we're in. Oh, it's a weird time.
