Who does not know the evils of war cannot appreciate its benefits.
If you are far from the enemy, make him believe you are near.
The consummate leader cultivates the moral law, and strictly adheres to method and discipline; thus it is in his power to control success.
Bring war material with you from home, but forage on the enemy... use the conquered foe to augment one's own strength.
Keep your friends close and your enemies even closer.
If the mind is willing, the flesh could go on and on without many things.
