The rules of friendship are tacit, unconscious; they are not rational. In business, though, you have to think rationally.
Friendship is unnecessary, like philosophy, like art... It has no survival value; rather it is one of those things that give value to survival.
The capacity to learn is a gift; the ability to learn is a skill; the willingness to learn is a choice.
Friendship is born at that moment when one person says to another, 'What! You too? I thought I was the only one.'
In the end, we will remember not the words of our enemies, but the silence of our friends.
It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change.
