Dan Brown, when asked this question by an interviewer following his meteoric success with his books.
No. I still get up at 4a.m. to write. And every morning I face a blank page. The characters don't care that I've made money. I have the same friends that I had before, and I'm married to the same wonderful woman. I drive a four year-old Lexus. I don't think about money. I have it, but I'm not drawn to fancy clothes, or yachts, or fancy cars.
