# Sun Tzu’s Strategy and Key Quotes Sun Tzu (c. 544–496 BCE) was a Chinese general, military strategist, and philosopher whose *The Art of War* remains one of the most influential treatises on strategy ever written. Its principles apply far beyond warfare—to business, politics, sports, negotiation, and personal conflict. Below is a structured overview of his core strategic concepts, paired with authentic quotes (translated from classical Chinese; variations exist across editions). --- ## **Core Strategic Principles** ### 1. **Know Yourself and Your Enemy** > *"If you know the enemy and know yourself, you need not fear the result of a hundred battles."*   > — Chapter 3 **Strategy**: Self-awareness + opponent analysis = victory. Assess strengths, weaknesses, resources, and psychology on both sides. **Application**: In business, conduct SWOT analysis on your company *and* competitors before launching a product. --- ### 2. **Win Without Fighting** > *"The supreme ar...
