All warfare is based on deception. Hence, when able to attack, we must seem unable; when using our forces, we must seem inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near.

In war, then, let your great object be victory, not lengthy campaigns.

The consummate leader cultivates the moral law, and strictly adheres to method and discipline; thus it is in his power to control success.

Whoever is first in the field and awaits the coming of the enemy, will be fresh for the fight; whoever is second in the field and has to hasten to battle will arrive exhausted.

Kill one, terrify a thousand.

You cannot know if you will be successful or not. You can only prepare for battle and it must be done with all of your heart and with all of your consciousness. In that manner, you will have an edge.

Opportunities increase as they are taken.
