I write on napkins. One time, this seventeen-year-old waitress says to me, “Do you write on napkins because it doesn’t count?” And bingo. That’s exactly why I do it! When you’re jotting on a napkin, you’re not committing yourself. It’s only a napkin, right? You can throw it away. You’d be surprised. It loosens you up. Some of the best stuff I’ve written has been done on napkins.
