"Today, your time was zero minutes." The reason why this question posed by a philosopher 2000 years ago resonates with you today. From the moment you wake up at dawn to when you fall asleep at night, your day is filled with tasks to handle, requests to respond to, and places to endure. You may have lived for sixteen hours, but how many minutes were truly for yourself? If this question takes your breath away, you are not alone. It was the same in Rome 2000 years ago. Lawyers waiting in line from dawn in front of their patrons' houses, citizens losing their time while handling lawsuits in the square; Seneca observed them and wrote, "When the grain in the granary decreases, we notice immediately. When the money in the vault leaks, we cannot sleep. But time? It slips away every day, and no one feels anxious about it." Philosophy of the battlefield, not the study Seneca is fundamentally different from other philosophers. He was not someone who sat in a study contemplating time. As a powerful figure in the Roman Empire, he spoke in the Senate, created laws, and coordinated diplomacy, struggling daily to safeguard his time amidst the pressures of life. His writings are filled with experience, not just ideas; they contain wounds, not merely theories. Even under the emperor's sword, he maintained his composure and lived as the master of his own time until he took his own life in 65 AD at Nero's command. His last words were, "The most noble legacy I leave is the way I lived my life." Montaigne kept him close throughout his life, Descartes referred to him, and Shakespeare drew from him Montaigne read Seneca over and over and was called "the Seneca of France." Descartes turned to Seneca's writings to discuss "What is happiness?" The archetype of Shakespearean tragedy comes from Seneca. Tim Ferriss produced an audiobook of Seneca's writings. The reason why the sharpest minds of the ages have returned to Seneca for 2000 years is simple: his insights on time, anxiety, and suffering transcend time.

Part 1 discusses the structure of stolen time (on the brevity of life), Part 2 covers how to manage a troubled mind (on peace of mind), Part 3 addresses the value of stopping (on leisure), Part 4 explores happiness that does not follow the crowd (on a happy life), and Part 5 examines how suffering shapes life (on providence). Each essay is self-contained and can be read in any order. The editor has one request: "Read an essay, pause for a moment, and ask yourself: What did this writing touch in me? That pause is the true value of this book."
