Most of my stories are ideas in action. In other words, I get a concept, and I let it run away. I find a character to act out the idea. And then the story takes care of itself.
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
