Witing is essentially interior work, and many writers are interior personalities. Having a job forces you out of the world of your work, and into the one in which you get to observe people. Yes, you can imagine all this, but as a fiction writer, you can never observe enough the rhythms of how humans move through the world. A job demands that you structure your time much more carefully. You learn how to be resourceful, and that in turn provides a certain intensity of focus.

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.

I wanted to write about the time when science became modern, around the 1950s. Right after physicist J. Robert Oppenheimer, science started being so politicized and used as such a political weapon. When my father, who is a scientist, tells me about those years, I get a competing portrait of people who were expected to behave normally and be decent respectable members of society and who were also allowed this freedom to think in big and expansive ways. Now, when you think about people who work in labs, they're allowed to be socially inept in a very fundamental 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.

Much of an editor's job is in fact pretty nanny-like in nature: in many ways, you're there to protect and defend, to reassure and clean up. What I ask from writers is respect. I want them to respect me enough to turn in a clean draft. I want that draft to be as good as they can make it. I want to feel the thought behind those words. And I want it to be turned in on time. It drives me wild when I get a story that's obviously slapped together, and the same can be said for a manuscript; you should respect your reader enough to give her something that reflects your best efforts.

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.

We're living in a literary age, at least in America, that is marked by a sense of distance, a coolness, in all senses of that word. To be too obviously, unapologetically emotional is to risk being considered foolish, or at the very least not serious.
