On the road, I encountered bushels of inconsistencies. The Swiss are uptight and happy. The Thais are laid-back and happy. Icelanders find joy in their binge drinking, Moldovans only misery. Maybe an Indian mind can digest these contradictions, but mine can’t. Exasperated, I call one of the leading happiness researchers, John Helliwell. Perhaps he has some answers. “It’s simple,” he says. “There’s more than one path to happiness.” Of course. How could I have missed it? Tolstoy turned on his head. All miserable countries are alike; happy ones are happy in their own ways.
