A friend of mine who is in the publishing business knew I was writing a book, and he said, 'Have you said anything yet about the good guy? Because I know you spend so much time with the bad guys.' Because they're fun. So then you have to make the good guy fun, in order to compete. That's the challenge.
I would say just start writing. You've got to write every day. Copy someone that you like if you think that perhaps could become your sound, too. I did that with Hemingway, and I thought I was writing just like Hemingway. Then all of a sudden it occurred to me - he didn't have a sense of humor. I don't know anything he's written that's funny.
I think any writer is a fool if he doesn't do it for money. There needs to be some kind of incentive in addition to the project. It all goes together. It's fun to sit there and think of characters and get them into action, then be paid for it. I can't believe it when writers tell me 'I don't want to show my work to anybody'.
