More quotes by Ray Bradbury

"Science 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."
"First you jump off the cliff and build your wings on the way down."
"The best scientist is open to experience and begins with romance - the idea that anything is possible."
"We are an impossibility in an impossible universe."
