Can do better

There is a middle condition of internal satisfaction with project quality. I think it call "it can be better". In my experience, it happens frequently that everything you produced a week ago met your internal standards for excellence, but as launch day approached, more and more things began to feel "not good enough."

The best strategy is to launch without further polishing. Almost always, horrible things happen before launches, and almost always, good things happen after launches. Perfectionism is impossible, and realizing this will save you hundreds or thousands of hours of work.
