My brother is a perfectionist who works in tech (as do I). I tell him that everyone needs at least 2 working speeds, and one of those speeds needs to be "quick" (aka "emergency"). I don't see it as a binary thing. You can be meticulous in the things that matter that they are done right, and quick for the things that need to be done. The metric for success in those things are different. Quickness is perfection in an emergency.
