Well stated, Peter T. I agree with you too. There's no one way that it works. There's often no one way it works with one person all the time.

However, I am usually very depressed after finishing a piece. It's a feeling of throwing in the towel, of admitting defeat, of knowing there's nothing more I can possibly do to make the thing any better. It's hit the point of diminishing returns and there's not a damn thing more I can do about it.
