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.

There are some writers who also enjoy being authors, and are good at it as well. There is nothing performative about writing, but there is about being a writer.

To be a scientist you have to be willing to live with uncertainty for a long time. Research scientists begin with a question and they take a decade or two to find an answer. Then the answer they get may not even answer the question they thought it would. You have to have a supple enough mind to be open to the possibility that the answer sometimes precedes the question itself.

I credit my parents for many things that had never seemed remarkable when I was growing up, and one of those things is how nonthreatened they were by my constant search for backup parents - other mothers and fathers would have bristled at this, but they never did. So I was always looking for other parental stand-ins, and I always found them.

My father collected turtles when he was young. My parent's wedding album, there's two pictures of them getting married and the rest are just pictures of turtles. I remember they had Galapagos tortoises that they had somehow imported illegally and a bunch of other turtles too. I like the animals themselves. They're so self-possessed and self-contained and there's something wise and mysterious about them. I also like that they are prehistoric animals.

I've never really understood the desire to be immortal myself. The idea of both wanting to live forever in some form and wanting to stay young forever just sounds exhausting. It's one of those desires that people think they want but when you actually stop to think about what it actually means, it's really awful. One of the reasons that life is bearable is because it's going to end soon. One of the main concerns of fiction is how do we make a life of 85 years or so meaningful.

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.
