Writing that flirts with incoherence can just as readily flounder as writing characterized by simplicity and composure. There is no reliable formula for originality, and strategies that are distinguished as innovative in their first incarnation can quickly become stale in the hands of lesser artists.
I feel there has to be a certain amount of improvisation as I'm writing, which means any idea or any commitment to a project is risky. It involves time; it involves gathering of material, and sometimes it just doesn't work. Sometimes it does. As I'm starting out on a project, I can't tell if it will click or not.
