Marcus Aurelius remains a guide for the perplexed because he doesn't offer easy answers or "hacks." He offers a rigorous, daily practice of the mind. He teaches that while the world may be a mess, your character doesn't have to be. You don't need to find a way to fix the universe; you only need to find a way to be the master of yourself.

If fame is fleeting and most of our worries will be forgotten in a century, we are free to focus on what matters right now: being a decent, rational human being in the present moment.
