Thus the skilful general conducts his army just as though he were leading a single man, willy-nilly, by the hand.

If you fight with all your might, there is a chance of life; where as death is certain if you cling to your corner

If I am able to determine the enemy's dispositions while at the same time I conceal my own, then I can concentrate and he must divide.

Opportunities increase as they are taken.

Other conditions being equal, if one force is hurled against another ten times its size, the result will be the flight of the former.

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.

Keep your friends close and your enemies even closer.
