"Well-being is an optimal state for an individual, community, society, and the world as a whole. It is conceived of, expressed, and experienced in different ways by different individuals and within the cultural contexts of different societies: different societies may have distinctly different culturally shaped visions of well-being. Nonetheless, well-being bears a degree of commonality due to our common humanity and interrelatedness over space and time. Well-being is experienced by individuals - its essential locus lies within individual subjectivity - but it may be considered and compared interpersonally and interculturally, since all individuals live within particular worlds of others, and all societies live in a common world at large."
Please remember these two bits:
1) The individual/s is/are the only measure of well-being.
2) There is no way of knowing/measuring how an individual is truly feeling/being.
Onwards Rocinante, to glory, to defeat the windmills of ill-being.
