In ancient Greece, the concept of arete was used to capture the idea of living up to one’s full potential and purpose. Arete was, in some sense, the earliest known incarnation of the modern self-improvement movement, encouraging the people to strive for continuous growth and excellence across a range of life areas, including relationships, intellectual pursuits, moral conduct, and more. The concept connects closely to eudaemonia, a state of flourishing happiness and fulfillment that is achieved only through seeking growth, meaning, purpose, and authenticity. The ancient Greek philosophers believed that through the pursuit of arete, the intentional life of growth and purpose, one can achieve a state of eudaemonic happiness.
