There is an unending amount that has been written about measuring happens and finding happiness etc... All of it seems to boil down to what I would consider "hedonism with a mortgage." The focus is on "lasting happiness" with relationships and experiences being there paramount, and de-emphasizes material accumulation and intoxication.
Nothing ever asks the question "why be happy anyway?"
Seems like it's as bad of a goal as any, but it's how our biological systems create action.
