A writer said to me the other day about book writing: "You're never going to make any money at it. It's just the satisfaction that you completed something." I paused, not for lack of words, but because I was processing where this mentality came from - this concept that if you're a writer then you're doomed to live in poverty. If you're writing for a hobby, then this may be true. A hobbyist will occasionally market their book and wait for sales. A hobbyist may have a website.
