“The problem with battling yourself is that even if you win, you lose.”
“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.”
“When you battle with your conscience and lose, you win.”
“know yourself and you will win all battles”
“Sometimes you lose a battle. But mischief always wins the war”
“Choose battles that you can win without losing your heart and your soul.”
