By happiness I mean here a deep sense of flourishing that arises from an exceptionally healthy mind. This is not a mere pleasurable feeling, a fleeting emotion, or a mood, but an optimal state of being. Happiness is also a way of interpreting the world, since while it may be difficult to change the world, it is always possible to change the way we look at it.
