Roman Emperor Marcus Aurelius Antoninus Augustus was the model of what we call a philosopher-king. Though his rule was troubled by war and conflict, he remained a thoughtful and even-handed ruler. Meditations isn't a complete book but rather a collection of his personal diary entries written over a ten-year campaign in Greece. The entries were never meant to be published; instead, they were a reminder to himself of how to remain calm, tranquil, and kind, even in the worst of situations. In them we see the emperor working out how to deal with the everyday problems all of us face: annoying coworkers, difficult family members, the expectations of others, and unrealized achievements, but ultimately finding happiness. The episodic nature of Meditations makes it hard to follow at times, but in exchange we get a deeply personal window into the life of one of Rome's wisest emperors and, more importantly, a handbook of thoughtful advice on how to live a tranquil, satisfied, and productive life.
