A wise man gets more use from his enemies than a fool from his friends.
“There is no higher rule than that over oneself, over one's impulses: there is the triumph of free will.”
“If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him.”
— Sun Tzu
“The wise are free from perplexities; the virtuous from anxiety; and the bold from fear.”
— Confucius
“He who is brave is free.”
— Seneca
