Sun Tzu was a Chinese general and philosopher who authored the influential military treatise The Art of War. The document outlines Sun Tzu's key principles for warfare and strategy, which focus on careful planning, assessment of strengths and weaknesses, deception, flexibility, and achieving victory without resorting to direct conflict. His teachings on strategy and leadership emphasize preparation, discipline, positioning, and gaining advantages over opponents. Though focused on military applications, Sun Tzu's principles have also been applied to business, management, and navigating conflicts in daily life.
