Eudaimonia
Etymology
From Greek "eu" (good, well) and "daimōn" (guiding spirit), literally the condition of having a good indwelling spirit. Central to Aristotle’s "Nicomachean Ethics," it is usually translated "flourishing" rather than "happiness" to stress that it is an ongoing way of living well, not a feeling.
noun · /yoo-dye-MOH-nee-uh/
A life of flourishing achieved by living virtuously and fulfilling one’s human potential, rather than merely feeling pleasure.
What it names
A richer target than “happiness” for talking about a good life — reach for it when you mean deep, activity-based fulfillment rather than a passing mood.
Example
He left the lucrative job that left him hollow, chasing eudaimonia over another bonus.
Related idea
Distinct from hedonism, which locates the good life in pleasure; eudaimonia can include hardship and effort so long as one is living excellently.
