That’s a really good question. I don’t think you ever know; you just have to make a call. Finishing is acknowledging that there’s no further progress to be made at the current juncture. If you sit on a song for 20 years and come back to it with all the wisdom of your life, you could probably write a better song, but objectively, you have to get it out into the world in order to continue to live as an artist. So, there’s a sense of: “well, this is as good as it’s gonna get for me at my level right now.” Sometimes you realize that early, but it can take a long time. I think deadlines were invented by God to make art possible. I don’t think I could finish anything without a deadline, self-imposed or external. With the book, it was just: these people at Penguin, they don’t know me. They have no idea that I can’t do this. I have to do it because otherwise they’ll know that I can’t do it.
