Ultimately there is no such thing as failure. There are lessons learned in different ways.
When I started thinking seriously about learning the rules of narrative, I thought, 'You've learned the rules of dancing from the ballet; what's the matter with learning the laws of theater from the people who know how to do it?'
I grew up in a drive-in theater, from the time I was 8, working in a snack bar watching four features every week. It was silent theater in the sense that this was a drive-in, which meant that I often saw the films going with no sound. But I learned to tell stories through action.
I've read probably 25 or 30 books by Balzac, all of Tolstoy - the novels and letters - and all of Dickens. I learned my craft from these guys.
I have to feel that each thing I've learned I can push to another point next time. I'm not very good with repetition. I would rather not work than feel that repetition is the order of the day.
