We know that happiness is not linearly related to material wealth. Above a certain level, the point where we personally feel we have ‘enough’, an increase in material wealth does not bring us more happiness. The pivotal point is this place where we have ‘enough’, whatever that might mean for each of us personally. Beyond that, joie de vivre seems to come about more readily from focusing our efforts more on the non-material aspects of our lives, for example our mental, emotional spiritual and physical wellbeing.
