That was my first time I've ever created a world that was not in some way my own. It started with picking up a Dobro—it had this nautical feel to it—and I said, This is almost a song about a guy who builds a submarine. And I went home and I obsessively thought about it.
The idea of this guy. Who are you? What are you doing? I've never been a novelist or a third-person sort of narrative writer, ever. But I got to know this guy. It was really emotional, I don't know why. Something sad about it.
You don't shoot ideas down before you have them. "That won't work," is the worst thing you can ever say. "That didn't work," is cool. But "that won't work," is not a way to go through life.
