Thus we may know that there are five essentials for victory: He will win who knows when to fight and when not to fight. He will win who knows how to handle both superior and inferior forces. He will win whose army is animated by the same spirit throughout all its ranks. He will win who, prepared himself, waits to take the enemy unprepared. He will win who has military capacity and is not interfered with by the sovereign.
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 TzuConvince your enemy that he will gain very little by attacking you; this will diminish his enthusiasm
Sun Tzu
