We're all products of what we want to project to the world. Even people who don't spend any time, or think they don't, on preparing themselves for the world out there - I think that ultimately they have for their whole lives groomed themselves to be a certain way, to present a face to the world.
Often times, I'm surprised by what I'm writing or what I'm playing, and then that inspires me to keep going with it, so it ends up being a very adventurous process.
