“Still, experience has taught me that knowing one's enemy is key to winning any battle.”
“Combat doesn't have to be with swords... Emotions can be deadly weapons, and knowing your enemy's breaking point can be key to winning a battle.”
“You have to choose your battles. The key is choosing the ones you know you can win.”
“No one has any experience of the battle of Armageddon.”
“Know the enemy and know yourself; in a hundred battles you will never be in peril. When you are ignorant of the enemy, but know yourself, your chances of winning or losing are equal. If ignorant both of your enemy and yourself, you are certain in every battle to be in peril.”
“To win one hundred victories in one hundred battles is not the acme of skill. To subdue the enemy without fighting is the acme of skill.”
