Don't think. Thinking is the enemy of creativity. It's self-conscious, and anything self-conscious is lousy. You can't try to do things. You simply must do things.
I know you've heard it a thousand times before. But it's true - hard work pays off. If you want to be good, you have to practice, practice, practice. If you don't love something, then don't do it.
You've got to jump off cliffs and build your wings on the way down.
You fail only if you stop writing.
Ray Bradbury (1920-2012)
