When you shoot a bow and arrow, you aim at the clouds, not because you expect to hit them, but so that you may reach the distant target on the ground.
Sun TzuYou can ensure the success of your attacks if you only attack places that are undefended. You can ensure the safety of your defense if you only hold positions that cannot be attacked. Therefore, that general is skillful in attack whose opponent does not know what to defend; and he is skillful in defense whose opponent does not know what to attack.
Sun TzuIn the tumult and uproar, the battle seems chaotic, but there is no disorder, the troops appear to be milling about in circles but cannot be defeated.
Sun TzuThe general must be the first in the toils and fatigues of the army. In the heat of summer he does not spread his parasol nor in the cold of winter don thick clothing. In dangerous places he must dismount and walk. He waits until the army's wells have been dug and only then drinks; until the army's food is cooked before he eats; until the army's fortifications have been completed, to shelter himself.
