The Art of War
Sun Tzu wrote this roughly 2,500 years ago and the strategic principles have outlasted every empire since. The core argument — that victory comes from preparation, self-knowledge, and positioning rather than brute force — has been applied to business, sports, leadership, and competitive thinking across cultures. Most editions run under a hundred pages, which makes it accessible in a way that belies its influence. Two honest caveats: the aphoristic style can feel frustratingly vague without strong commentary or a good translation, so edition choice matters. And the book treats deception as a central strategic virtue, which sits uneasily with faith commitments to honesty. Worth reading, but engage it critically rather than adopting every principle wholesale.
