Sometimes the most difficult thing you can do as an editor is not make a single note - the idea that everything and everyone needs editing is, in reality, a fiction. I've gotten pieces where I thought, Well, I could do this or that, or change this word, but in the end, I leave it. Changing something is not necessarily equivalent to making the piece more true to itself, which is the point of editing: it's just changing it because you feel you can or should or must.

When you don't have to depend upon your creative work for money, you'll never really have to compromise... Knowing that is hugely liberating as well as artistically clarifying... Being practical about where your money comes from means you can be romantic about your writing... I believe that a healthy society is one that supports its artists, but I also know that that privilege, of being only an artist, is afforded to just a small number. Most of us have to find something else - or live a highly disciplined life, which I'm not willing to do.

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.

If you start asking how do we make life meaningful and life never ends, then you get into sort of these terrible sort of metaphysical quandaries and it gets really, really bleak looking.

As with editing, I think my strength as a writer is structure. It's not a skill that's much discussed when we discuss fiction, or not as much as language or character development anyway, but it's the first thing I determine before I begin writing - not just books, but anything. I think I know how to pace a narrative well. I think I'm aware of repetition, that I try to create different kinds of sentences as often as I can. Those are all things I learned from magazine editing.

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.

When you're young, your perception of what it means to be a writer is often less about the writing and more about what seems to be the accompanying life: speeches and travel and hanging out with other writers. You think that when you get published, your life will clarify itself to you somehow. But when you don't get published until you're middle-aged you know who you are already, and your life expands to make room for your writing, rather than orbiting around it. You realize that there's no one way to be a writer, and that the job is less of an identity and more of a vocation.
