“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.”
“The problem with battling yourself is that even if you win, you lose.”
“Do not forget: seek to win all your battles, including those you fight against yourself. Do not fear the scars. Do not be afraid of victory.”
“You don’t always win your battles, but it’s good to know you fought”
“If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.”
