If you know the enemy and know yourself you need not fear the results of a hundred battles.
The supreme art of war is to subdue the enemy without fighting.
Regard your soldiers as your children, and they will follow you into the deepest valleys; look on them as your own beloved sons, and they will stand by you even unto death.
A good commander is benevolent and unconcerned with fame.
Pretend inferiority and encourage his arrogance.
