It's interesting because when David Fincher was making "Fight Club," he said, "It's a romance." And it really is. Almost everything I ever write is just a romance. And that needed to be sort of pointed up at the end of "Fight Club." The film has a very different ending than the book does.

It seems like the sort of archetypal American issue. If you're given the freedom to be anything, or be anyone, what do you do with it?

I take pens and I write on the inside of my arm. When I'm with people and somebody says a really fascinating anecdote, or fact, or phrase, I'll write it on the inside of my arm. At the end of the day, I'll take the very best things that are on my arm and I'll copy them into a notebook that I always carry and only when the weather is absolutely terrible will I really key the very best of that notebook into the computer. At that point, it's all sort of censored twice - only the best things go from the arm to the book and only the best things go from the book to the computer.

Real writers write because they love to write. They don't write for public acclaim.

Some people still think knowledge is power.
