Well said, on the whole. It is useful to distinguish between two kinds of happiness which the Greeks designated as hedonia and eudaimonia. The first is the momentary gratification we all get from experiences we enjoy, whether it’s music, chocolate, sex, fishing, or conversation with family or friends. It is pleasant and gratifying, but it never lasts. Eudaimonia (lit. Good spiritedness) is the deep, adamantine peace of mind that comes of cultivating benevolence and compassion, and is manifested as quiet, selfless joy and equanimity.
