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.

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'm not sure a person ever really reveals the whole of himsels or herself to another person, and I'm not sure we should. Or rather, just because you don't, it doesn't mean you can't have a meaningful relationship with another person. It's important to remember that this idea of confessing your most shameful, embarrassing stories and self to someone else as an expression of love and intimacy is a relatively recent phenomenon, and a new definition of what it means to be close to someone. After all, the self is by its nature secretive.

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 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.

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.

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.
