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.

I was fortunate to be at that school in an era in which encounters between students and teachers were encouraged; there were a number of teachers who lived on campus, and they'd regularly invite students over for dinner on the weekends. I hope it's still like that: being treated seriously by an adult you admire is a great gift. Children, like adults, want respect - but it's only when you're older that you realize how few people actually extend it.

I know I'm a better editor than I was when I began, twenty years ago. I'm less scared of the text, I'm less scared of the writer, and, crucially, I no longer believe that I have to leave my mark on every story.

Health insurance, which is exceedingly difficult to secure as an individual in New York. Obamacare, while certainly better than nothing, is pretty awful, and if you have a complicated health history, as I do, you need premium insurance, which means private insurance. The challenge, though, is finding a company that will give you the privilege of paying up to $1,400 a month for it. When I didn't have a job, I spent more time thinking about insurance - not just paying for it, but securing it in the first place - than I wanted to.

I'm an indulgent writer - I'm not sure, however, that's something I'm interested in changing. Writing should be indulgent: you should take big risks on the page, you should make big mistakes, you should be excessive at times. I let myself do as a writer what I probably would be less likely to allow as an editor.

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 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.
