“It's incredible how much stamina you can find when you're fighting and enemy in battle, even if that enemy is just in your imagination.”

“Know your enemy and know yourself and you can fight a hundred battles without disaster”

“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 fight and conquer in all your battles is not supreme excellence; supreme excellence consists in breaking the enemy's resistance without fighting.”

“Hence to fight and conquer in all your battles is not supreme excellence; supreme excellence consists in breaking the enemy's resistance without fighting.”

“There are some battles, no matter how much you don’t want to fight them, that you just have to fight. That are worth giving your life for.”
