I'm a physical actor in that I start with a physical sketch of the character. I find it easier to find inspiration from the outside in. If I find the character's tensions and the way he carries himself or looks, that's going to affect how I talk. So that's how I start to create that person.

I always say three things make a writer: inspiration, obviously; perspiration, doing the work. But the third is desperation. I'm not really fit for anything else, or to have a real job. That fear drives me. The pressure has always been self inflicted.

I've heard people on panels say, 'You must have a Web site. You need to tweet. Repeat the title of your book constantly,' and I just want to say, 'Shut up. Everything you're saying is wrong.' People will know instantly if your only motivation for tweeting is to sell books.

The crowd could be tough to deal with at times, but I learned to use them and the way they behaved towards me as strong motivation.
