Being unconquerable lies with yourself; being conquerable lies with your enemy.

In all fighting, the direct method may be used for joining battle, but indirect methods will be needed in order to secure victory.

What is essential in war is victory, not prolonged operations.

Move not unless you see an advantage; use not your troops unless there is something to be gained; fight not unless the position is critical.

A battle avoided cannot be lost.

Appear at points which the enemy must hasten to defend; march swiftly to places where you are not expected.

It is more important to outhink your enemy, than to outfight him
