You can do "perfect". Or you could do better. Better means you might not be done, but you did take another step in the right direction. Progress is still needed. Questions are still on the run, yet to be answered. You're not at the peak yet. In fact, you're not even sure that there is a peak, or a finish line. The only thing you're sure of is that you are getting better at going on this journey each and every day, wherever it may be taking you. Better means that things aren't over. You're not there yet, but you're well on your way.
I don't know about you, but perfect sounds pretty boring to me. It's also impossible.
I'll take better. Better is better.
