Perfection is the enemy of greatness. We as people are limited in the knowledge and information we have, so to say one has reached all of the highest standards of what is known as the conventional consummation of human excellence means there is nothing more they would have to learn. This of course, is impossible, for there are always new things to learn, and so perfection is unachievable and unattainable.
A friend is someone who knows all about you and still loves you.
