We live in times of immense and ongoing change. That frightens people. Fear, however, is the worst advisor in all that we do. The best is hope, even in the most difficult circumstances. Over the course of years of travel and research, writer Leo Bormans determined that "happiness is the ultimate motive for what we do" and love is our highest emotion. But what inspires us to actually take action? Hope. In this uplifting anthology, 100 scientists and scholars from around the world share their discoveries about the power of hope. From secretary general of the United Nations Kofi Annan's testimony about the importance of dreaming and psychologist Robert Biswas-Diener's take on optimism, to behavioral scientist Christopher Boyce's argument for personal change and economist Nicole Fuentes's research into the link between happiness and hope, the short essays in The World Book of Hope create a heartening "textbook" for anyone seeking encouragement and inspiration.
