The first thing a writer should be is - excited. He should be a thing of fevers and enthusiasms. Without such vigor, he might as well be out picking peaches or digging ditches; God knows it'd be better for his health.
Ray BradburyScience fiction is any idea that occurs in the head and doesn't exist yet, but soon will, and will change everything for everybody, and nothing will ever be the same again. As soon as you have an idea that changes some small part of the world you are writing science fiction. It is always the art of the possible, never the impossible.
Ray Bradbury
