Really capable people study history not to remember how many dynasties and figures there were, but to understand human nature, reduce internal conflicts, and make the right choices. The essence of history has never been about the events themselves, but about people's judgments and choices at critical moments. Reading history allows people to step outside immediate gains and losses, view problems on a longer time scale, and avoid being trapped by temporary emotions and evaluations; it also helps people understand the patterns of human nature, grasp interests, strategic interactions, and boundaries, and stay clear-headed without losing their bottom line in complex relationships. More importantly, history is a vast case library that provides reference points at life's crossroads, preventing impulsiveness, greed, and extremism. While times are constantly changing, human nature remains interconnected. Skills solve survival problems, and history shapes our cognitive framework. It may not make someone successful overnight, but it helps people maintain steadiness in anxious times, stay calm in lows, remain humble in highs, and live with clarity and purpose.
