War is a matter of vital importance to the state.

Against those skilled in attack, an enemy does not know where to defend; against the experts in defense, the enemy does not know where to attack.

The difficulty of tactical maneuvering consists in turning the devious into the direct, and misfortune into gain.

The essential factor of military success is speed, that is taking advantage of others' unpreparedness or lack of foresight, their failure to catch up, going by routes they do not expect, attacking where they are not on guard. This you cannot accomplish with hesitation.

If it is to your advantage, make a forward move; if not, stay where you are.

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