I always market research my books before I hand them in by showing them to five or six close friends who I trust to be honest with me, so they are very heavily re-written already.
For the most part, having more money and more fame make your life harder. It just does. I've seen it happen with people. You know, it's so hard to stay normal. It's so hard to stay happy. It's hard to remember why you were doing what you did in the first place.
