The one who figures on victory at headquarters before even doing battle is the one who has the most strategic factors on his side.
Sun TzuThe value of time, that is of being a little ahead of your opponent, often provides greater advantage than superior numbers or greater resources.
Sun TzuBring war material with you from home, but forage on the enemy... use the conquered foe to augment one's own strength.
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.
