I believe in a business boarding up early. If you make a mistake, you put the boards in the window of the store and say, "Hey, I made a mistake." Let me take two shots in the arm and a punch on the nose and let me get on to the next thing. I don't believe in worrying over failures. I worry about successes. This is opposite from most people. Most people zero in on their failures. I try to keep all my attention on a pyramid type philosophy rather than the averaging-down philosophy.
Also our fellow competitors, who are indeed the people just mentioned - we do not compete with men who lived a hundred centuries ago, or those yet not born, or the dead, or those who dwell near the Pillars of Hercules, or those whom, in our opinion or that of others, we take to be far below us or far above us. So too we compete with those who follow the same ends as ourselves; we compete with our rivals in sport or in love, and generally with those who are after the same things; and it is therefore these whom we are bound to envy beyond all others. Hence the saying.
An athlete experiences the emotions of pain and elation through triumph and defeat, through teamwork and individuality, as nothing more than a human being...that is the true glory of sport.
Youth is full of sport, age's breath is short; youth is nimble, age is lame; Youth is hot and bold, age is weak and cold; Youth is wild, and age is tame.
Invincibility is in oneself, and vulnerability is in the opponent. Invincibility is a matter of defense, vulnerability is a matter of attack. Therefore skillful warriors are able to be invincible, but they cannot cause opponents to be vulnerable. That is why it is said that victory is discerned and not manufactured.
