One of the things you learn from finishing creative stuff is that even though it isn't perfect, it's meaningful, and you can be happy with it. Even embarrassing or bad works, though you may or may not want to show them, have their own being and meaning. You can sense this distinctly and be happy in some little way with all your children, yet this isn't complacency. It's fuel. Do what you can at the time, finish a bad piece: initial discouragements aside, you'll want to make more, you'll have more ideas to try, and you'll have levelled up in finishing what you start.
