You don’t have to be happy all day today. No one’s going to force you. But the International Day of Happiness, established by the United Nations in 2013, is more than just a pipe dream that people will try to be happier for one day a year. It’s part of a campaign to “end poverty, reduce inequality, and protect our planet,” all things that should be conducive to greater overall happiness. And, just as Bhutan doesn’t measure its progress by GDP but rather Gross National Happiness, today is a day to remember that there’s much more to happiness, and to a fulfilling life, than financial achievement.
