What common mistake do people make regarding happiness, according to Epicurus?

Epicurus highlights that many individuals misunderstand the source of their happiness by associating it predominantly with external factors such as wealth, relationships, and material possessions. He argues that this approach is misguided because the pursuit of such external goods often leads to anxiety, dissatisfaction, and an endless cycle of wanting more. Instead, Epicurus emphasizes that true happiness stems from simple pleasures, mental peace, and the cultivation of inner tranquility.

By recognizing that happiness is not solely tied to material wealth or social status, Epicurus encourages a shift in focus towards enjoying life's simpler pleasures, fostering meaningful connections that aren't based solely on utility or status, and finding contentment within oneself. This insight challenges the common belief that happiness is achievable through the accumulation of external goods, advocating instead for a more introspective and philosophical approach to well-being.
