(You save £4.00)
The world has reached unprecedented levels of wealth, but while we have succeeded in getting richer, we have failed in getting happier. While many people live lives of quiet desperation, a few people find themselves at the very top of the scale when it comes to happiness. Their behaviour is different. Their outlook is different. Their priorities are different. What can we learn from the world's happiest people? Condensing years of research from The Happiness Research Institute, hundreds of interviews, and thousands of studies and experiments - including new studies and experiments on smiling and the effect of social media on happiness - into a comprehensive, easy-to-read and beautifully illustrated guide to finding everyday happiness.
