It is always sort of unnerving to hear from people who've read my books. I'm not reading any of the reviews and most of my friends haven't read it - they bought it, which is all I frankly care about, but they haven't read it.

I always wanted to be a scientist. I don't really have any writer friends. The process of being a writer is much more interior than being a scientist, because science is so reactionary. I think that all research scientists think of themselves as belonging to a grand tradition, building on work that has been worked on since the very beginning of science itself. Whereas I'm not sure writers think of themselves in the same way.

My great strength as an editor, I believe, is structure: I know how to reorder a piece, I know how to reach into a jumbled story and extract the important narrative. And I can do both of these things very fast. I also think I've become better at cutting text. You don't always relish it, of course, but by now I know how to distill something without sacrificing its essence.

I was fortunate because I had parents who believed that being a writer was a perfectly acceptable thing to want to be. They'd actually hoped that I might be an artist, and I was lucky again to grow up with people who delighted in making things: my father wove baskets and painted furniture and carved wood figures; my mother quilted and embroidered and sewed.

When you're 21 you think, "Old people sound like this. Old people think like this." I don't think my ideas about aging and about eternal life changed that much, but it became more poignant to me as I did get older and I could better imagine, as you sort of inch closer to death every day, why legacy, more than aging, becomes important to people.

Now, almost twenty years since my last job in book publishing, I know that there are far more socially inept people in book than in magazine publishing. At the time, however, I just didn't feel I was enough: smart enough, savvy enough, well read enough, educated enough, charming enough. Much of this was probably because I was very naive, and didn't really know how to behave in an office. This made me a terrible assistant, which in turn made me a terrible junior book editor.

I have one friend to whom I've told more than I've ever told anyone, and yet there are significant territories I have and will never let him access - in large part because I'm trying to protect him, and one of the responsibilities of loving someone is protecting him or her, even if who you're protecting them from is yourself.
