Today, March 20, 2013, marks the first ever International Day of Happiness. This was decreed last year by the United Nations following a meeting on well-being attended by government officials, economists, scholars, and business and spiritual leaders from around the world. It was hosted by Bhutan, a small but visionary country which famously uses Gross National Happiness (GNH) instead of Gross Domestic Product (GDP) to index its progress.
