The Good Life: Where Psychology Stands On Living Well

The point is that as it has been said, science is just common sense, systematically applied. Just a quibble with the snippet. I would put "feeling healthy and safe" at the top of the list. It's the necessary, but not sufficient condition for everything else.

The Good Life: Where Psychology Stands On Living Well:
"So far we have learned from psychology that a good life includes experiencing more positive than negative feelings, feeling like your life has been lived well, continually using your talents and strengths, having close interpersonal relationships, being engaged at work and other activities, being a part of a social community, perceiving that life has a meaning, and feeling healthy and safe. And while these conclusions may seem like common sense, we as humans fall short on knowing just how to obtain and maintain these qualities.

Psychology still has a ways to go until the perfect formula for a good life is found. As Park and Peterson put it, "At present, psychology knows more about people's problems and how to solve them than it does about what it means to live well and how to encourage and maintain such a life." They suggest researchers across all disciplines of psychology come together and collaborate on their findings, perhaps pulling together a more complete picture of the human experience.
