Perfect doesn't mean flawless. Perfect means it does exactly what I need it to do. A vacation can be perfect even if the nuts on the plane weren't warmed before serving.
Any project that's held up in revisions and meetings and general fear-based polishing is the victim of a crime. It's a crime because you're stealing that perfect work from a customer who will benefit from it. You're holding back the good stuff from the people who need it, afraid of what the people who don't will say.
Stop polishing and ship instead. Polished perfect isn't better than perfect, it's merely shinier. And late.
