Many writers write across difference of one kind or another. Sometimes the difference is large and recognizable: gender, or race, or religion, or sexuality. And sometimes the differences are smaller. ... Where authors get into trouble is in trying to make those different characters stand in for whole groups of people, or for creating characters only to fetishize or explore their supposed otherness. Your character can be wildly different from you, as long as he's written with respect and, moreover, specificity.

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.

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.

Does people not asking me about Asian American literature mean they don't see it as its own literary tradition? I certainly believe in it as its own literary tradition, because your race plays a great factor in how you are seen by the world, and how you see the world; the fact that I'm an Asian American isn't incidental to who I am as a writer. Where it becomes difficult is defining what, if anything identifiable at all, makes an Asian American book an Asian American book, other than the fact of its creator being Asian. And I'd argue that there is nothing identifiable beyond that.

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.

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.
