"The World book of happiness is an extraordinary project. Leo Bormans approached over 100 of the world's leading experts in positive psychology--from 50 different countries--to write a short essay, based on their original research, addressing what they have learned about happiness. This resulting book provides clear insights based on worldwide scientific research with real people. The subjects tackled include time, health, success, well-being, money, the future, compassion, genetics, free will, humor, pain, family, friends and more. It not only explores the individual, but also the well-being of organizations and nations, resulting in a unique global vision of happiness." -- Cover, p. [4].
