I know the structure of the entire book before I begin... I begin the day by reading what I wrote the day before or maybe for the last two days, and cleaning it up, making sure it says what I want in the way I want to say it. When I get to the end of that, I want to know what happens -- so I start writing more! The only part in my writing day that I keep a pretty strict schedule is making sure I get enough sleep so I can think clearly.
Fantasy allows you bend the world and the situation to more clearly focus on the moral aspects of what's happening. In fantasy you can distill life down to the essence of your story.
"...'good' is not necessarily the same thing as 'salable'; you know that your own writing is good, in the same way that you know whether any book is 'good.' Is it interesting? Do you want to know what happens next? Or are you bored, and keep saying to yourself, "What's the matter with this person, why can't they spell?"" -- Diana Gabaldon
