If anything, I've found nonfiction a little easier. You don't have to make anything up. Of course, that's the inherent difficulty as well: when you hit an information black hole, you don't get to make it up. That hasn't come up too often with this project though. I'm lucky to have tons of primary source material , reams of letters and diaries and memoirs.

I always think, OK, this is good, but I'll do it better next time. "And so we beat on, boats against the current. . ." It may not be the recipe for a life of contentment, but that imperfectability is what makes writing such an engaging endeavor, something you can do for the rest of your life and not get bored.

Once I had started, I discovered the secret pleasure of writing a novel. It's such an immersive, deep commitment. With short stories, you're continually having to start again from scratch, but with a novel you only need one good idea every few years.

Unless you're Stephen King or Joyce Carol Oates, no one's going to recognize you on the street, and you're promoting your book, not yourself.

I figured that to be a writer I would need to have been born in the nineteenth century, be British, or have three names. So I turned my sights elsewhere . . . to acting.

If you had told me twenty years ago that I would write a novel set in Russia, much less two, I simply wouldn't have believed you. I had no familiarity with Russia or its history, but part of what drives me as a reader, and more and more as a writer, is curiosity, the desire to explore unfamiliar terrain and inhabit alternate lives.

You're unusual. That's better than popular if you have some courage.
