"As a rule, I take a piece of paper and a pencil and for 12 minutes nothing is written in your head without editing, without censorship, just to get it out of your mind. After that it gets read and the paper is destroyed immediately. It's very good to write a song with what has been left in your memory, without reading it again. It's as if you chose the best, the memory is that selective... Do you know what is also good for creativity? Write fast. Once a week, don't eat for 24 or 30 hours. Your brain becomes very lucid about ideas."
