Sun Tzu wrote this classic treatise on warfare approximately 2500 years ago, during a time of great political uncertainty and sweeping military campaigns. Written simply without fanfare using military scenarios and recommended responses, The Art of War has proven to be inspirational to many people who have applied its theories in every day life.
All warfare is based on deception.
Hold out baits to entice the enemy. Feign disorder, and crush him. If he is secure at all points, be prepared for him. If he is in superior strength, evade him. If your opponent is of choleric temper, seek to irritate him.
