When pursuing a search example posed by Cassius I came across this: "Epicurus believed that the ultimate aim of a happy life is 'freedom from pain in the body and from trouble in the mind'". I don't know if this is a quote from this site or from elsewhere.
However, it raises the question: is the "ultimate aim" a happy life or a relevant, contributing life? The former seems so narcissistic.
Thoughts, perspectives? (Or, have you already talked that into the ground?)
