A writer of fiction lives in fear. Each new day demands new ideas and he can never be sure whether he is going to come up with them or not.
If you write, one of the questions you're always trying to answer is, Where do you get your ideas? And, if you write, you know how pointless a question this is and how difficult it is to answer.
Realism is a bad word. In a sense everything is realistic. I see no line between the imaginary and the real.
