Sun Tzu- The Art of War

If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.

Let your plans be dark and impenetrable as night, and when you move, fall like a thunderbolt.

The supreme art of war is to subdue the enemy without fighting.
