So I realized when I was successful in a piece, it was because I didn't abandon a notion early on what it ought to be, and I let it take me along. So I've had songs that started out as being about the environment and ended up being love songs and love songs that ended up being about the environment. I've had things that I thought would be a poem and realized that it was just too big for that. I've got to do something larger and it became a play. I wrote one poem that started a whole play.
