I think partly this is because we are less creative when we have a lot of preconceptions about how a “proper” work is supposed to go. It’s supposed to be hard, for example. Throwaway work can be free of those preconceptions because one isn’t taking it seriously. What one ends up spontaneously creating can thus turn out to be more valuable. I’m sure I’m not the only one who finds Sweet Child to be the only memorable thing they ever did.
