“If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him. If your opponent is temperamental, seek to irritate him. Pretend to be weak, that he may grow arrogant. If he is taking his ease, give him no rest. If his forces are united, separate them. If sovereign and subject are in accord, put division between them. Attack him where he is unprepared, appear where you are not expected .”
― Sun Tzu, The Art of War

“Let your plans be dark and impenetrable as night, and when you move, fall like a thunderbolt.”
― 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.”
― Sun Tzu, The Art of War

“Victorious warriors win first and then go to war, while defeated warriors go to war first and then seek to win”
