What are the determinants of a happy and fulfilling life? This is surely one of life’s biggest questions, and a question that has interested many of our ancestors. Buddha famously gave up his kingdom in search of happiness. Several Greek philosophers (from Aristotle to Epicurus and Plato to Socrates) had their own views on what it takes to be happy.
And of course, we all have our own theories about happiness too. How valid are our theories? Until recently, if you wished for an answer to this question, you would’ve been forced to base it on discussions with spiritual leaders. Or, if you were lucky, you could’ve based it on late-night (and perhaps intoxicant-fueled) conversations with friends and family.
