Every battle is won before it is fought.

Therefore I say: 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 of yourself, you are certain in every battle to be in peril.

If the enemy opens the door, you must race in.

The general who advances without coveting fame and retreats without fearing disgrace, whose only thought is to protect his country and do good service for his sovereign, is the jewel of the kingdom.

He whose ranks are united in purpose will be victorious.

Concentrate your energy and hoard your strength.

Swift as the wind. Quiet as the forest. Conquer like the fire. Steady as the mountain
