If you know both yourself and your enemy, you can win a hundred battles without a single loss.
Sun TzuThe best victory is when the opponent surrenders of its own accord before there are any actual hostilities...It is best to win without fighting.
Sun TzuNow a soldier's spirit is keenest in the morning; by noonday it has begun to flag; and in the evening, his mind is only on returning to camp.
