Those who know New York City primarily through tourism or mass culture may think of us natives as possessing certain shared characteristics, not all of them flattering. But the true, volatile charisma of New York lies in how balkanised it is.

I personally feel I still have so much to learn as a writer; each novel is better than the one before, just because I'm getting better at it.

Luckily for you, you can close the book The Postman Always Rings Twice and break out of it, and James M. Cain can't. I can't think of any redeeming feature he has, but he's extremely compelling.

The first draft of everything, I write longhand. One of the nice things about that is that it makes you keep going. If you write a bad sentence on the computer, then it's very tempting to go back and fidget with it and spend another 20 minutes trying to make it into a good sentence. When you're handwriting, you really just have to move on.

That's really the essence of what any fiction writer does. Some of it is research-based, but most of it is a really long-term, imaginative, empathetic effort to see the world the way someone whose experiences remote from yours might see it. Not every writer works that way; some writers make a wonderful career out of writing books that adhere very closely to how they view the world. The further I go with this, the more interested I get in trying to imagine my way into other perspectives that at first seem foreign to me.

I hesitate to say yes - I had writer's block, because I know there are people who've had really serious cases of it, and I've never been paralyzed like that, but I definitely get blocked sometimes. More than periods where I don't write anything, I have periods where I just write junk and I know I'm writing junk but I can't stop.

Another big moment in terms of that feeling was David Petraeus: if the director of the CIA can't get away with having a secret relationship, then what hope do you have? It's not really an original idea, but there's something that goes along with power and celebrity that starts to make you feel like you're impervious to certain forces that the rest of us have to live with.
