Accuracy requires attention, care, and thoroughness.
Perfection is flawless. There is no possibility for improvement. Striving for better cannot exist with perfection.
The bull's eye on the dart board is larger than the point of the dart. You can get really close and still earn top points. Accuracy pays off.
Perfection, on the other hand, provides no chance to learn or to improve. In addition, perfection cannot share its space with anyone (or anything) else. There is only room for one, so sharing is not possible.
