We all strive for it (okay, maybe not everyone). But, is it possible to reach the point where we can no longer improve? God, I hope not. Life sure will get boring.
I believe in being very very good. But perfect? To achieve the level where mistakes are never made, and there are no questions within our minds, would be horrifying? The road to achieving a goal that can never be attained though, is very adventurous.
Best of luck to everyone, in their quest for perfection. It's fun isn't it?
