jaap, Really enjoyed reading this article from Oishi and Westgate on “A Psychologically Rich Life”. As a potential third dimension next to Hedonic (Pleasure) and Eudaemonic (Meaning) Wellbeing, they posit the notion that Psychological Richness leads to Wisdom. It allows for a reframing of experiences that don't fit the happy/meaningful box, but do add to increased wisdom in life.
I'm working on a blog post to be more coherent about this...
