Writing is a bit like walking into a big bookstore. It's the bookstore of your brain, and you know you're never going to read all those books. It makes you happy you're in the bookstore, and you're nervous because you know you're never going to read all those books. So the nervousness is also happy. Once I get going writing poetry is one of the happiest things I do, but it is also fraught with all of these anxieties.
