I know great songwriters. Fred Neil would come up when he was in L. A. , we all used to hang out. He would sit there and sing, and we would just melt. I mean, we would go to his recording sessions.
Think about a piece of music - some great symphony - we don't expect it to get better as it develops, or that its whole purpose is to reach the final crescendo. The joy is found in listening to the music in each moment.
