As head of TED, Chris Anderson has had a ringside view of the world's boldest thinkers sharing their most uplifting ideas. Inspired by them and the unique insights he gained from how online sharing transformed TED into a global beacon of transformative ideas, he believes there's a pathway back from outrage to optimism. It all comes down to reimagining the role that generosity can play in our connected era. Anderson shows how the same technologies that have bred negativity can also be mobilized as an exponential force for good, to create chain reactions of generous behavior. Every day, remarkable stories of individual acts of kindness have sparked ripple effects when shared online. This book captures some of the most inspiring of these stories, revealing their potential to solve problems and make people happier in the process.
