We all want to be happier. But is it possible? This book offers a resounding 'yes', by using reasoned ethics and offering a mass of empirical evidence. There is now abundant experiment evidence on how we can build a happier way of life. It speaks to individuals who want to live better and it speaks to the many policy-makers who think there is more to life than GDP. Using this evidence, the book shows chapter by chapter what can be done by teachers, managers, healthcare workers, community leaders and scientists - as well of course, as economists and politicians. But above all it addresses us as individuals, showing how we can live better lives, especially with the help of movements which bring people together in community groups to support happier living. Does this agenda have any hope of taking off? This book says it already has.
