The End Cap of Excellence

When is it like perfectionism? And there's never ends, right? When are you excellent at something? Seems like the way you're describing it here. It means once is ready to do the stuff I intended it to do, is that excellence already or am I getting it? Well, I mean, there's always levels of proficiency that you can strive for. So maybe it's like when you think about an internal combustion engine, no engine's like a hundred percent efficient, right? You study that in physics, but you can make it as efficient as possible by using the right fuel and making sure everything is operating in the best way possible.
