They certainly have, @npub1tsgw6pncspg4d5u778hk63s3pls70evs4czfsmx0fzap9xwt203qtkhtk4 . The concept of eudaimonia has taught me that happiness is not a feeling but a state of mind. A state of complete contentment. The concept of wisdom motivates me to do my best to make progress. And the idea that wisdom that is all that is needed for happiness inspires me to take full responsibility for my own life and to stop wasting time on things that are inconsequential to happiness.
