Julia, Thank you for this excellent article! You fully explored linguistic variations for happiness. I especially like this quote on eudaimonia:

In Britannica, it’s said,

“For Aristotle, eudaimonia is described as the highest human good, the only human good that is desirable for its own sake (as an end in itself) rather than for the sake of something else (as a means toward some other end).”

I favor the enduring happiness of eudaimonia, even though it may seem elusive at times. I strive for eudaimonia in life. So much fine insight in your piece!

My best wishes, Amy
