My favourite email bulletin is the Visual Capitalist infographics. These brilliantly represent current data and trends in a format even I can understand.
However, this one flies in the face of most studies I’ve seen (and I read all I can; it’s a subject which fascinates me).
So, it looks like we need about $80k pa to start being happy. Other studies have suggested that above about that amount, earning more doesn’t have a significant effect on happiness.
