Three thousand years ago on a battlefield in ancient Palestine, a shepherd boy felled a mighty warrior with nothing more than a pebble and a sling, and ever since then the names David and Goliath have stood for battles between underdogs and giants. David"s victory was improbable and miraculous. He shouldn"t have won. Or should he have? In the tradition of Gladwell"s previous bestsellers - The Tipping Point, Blink, Outliers, and What the Dog Saw - David and Goliath draws upon history, psychology, and powerful storytelling to challenge how we think about obstacles and disadvantage, and to fundamentally reshape the way we think about suffering and adversity.
