Whether a Great Transition occurs is, to a great extent, a matter of choice. “Push” (necessity, avoidance of risk/harm) and “pull” (pursuit of attractive options) will guide our collective decisions. Well-being is an important pull. Our understanding of well-being will, in part, shape the choices we make, individually and collectively, as we create our future. A broad, sophisticated understanding of well-beng is essential if we are to choose wisely. Accordingly, this paper reviews various perspectives on well-being and offers its own conception: the well-being mandala, a nested image of various facets of personal well-being residing inside broader social and environmental well-being.
