tl;dw: Happiness is fleeting, chasing an emotion is intrinsically difficult/impossible. too often we say we want team happiness but what we really want is happiness of specific members whom we consider important, thereby creating a two class system(at which point she makes reference to the holocaust?). what we really want is equanimity on our teams, i.e. calmness. This allows for more nuanced discussion of issues, because when you optimize for happiness you and your team can hide reality from one another in order to ensure happiness.
feel free to add anything i missed, it was an hour long and I zoned out during some parts.
