Marcus Aurelius reminds us that happiness is not found in external accumulation but in internal transformation. The essentials for a fulfilling life are surprisingly few - good health, basic needs met, meaningful relationships. Beyond these basics, happiness becomes a matter of perspective and mental approach. By changing how we think about our circumstances, we can find contentment with what we have rather than constantly seeking more. This isn't about settling for less, but about recognizing that our attitude toward life determines our experience of it more than our external conditions do.
