Why does the teacher put "Well-Being" in the course title, instead of "Happiness", even when the course is totally about happiness? Does this mean happiness is the same as well-being? I highly doubt it.
Someone who is in a very good position, and general state of well being will have bouts of every emotion, and surely won't be 'happy' in every moment.
Though surely one could make the case that 'general happiness' and 'general well being' are the same thing if they wanted to.
