Author Malcolm Gladwell writes a compelling narrative about the how life events or circumstance that may seem to be a disadvantage are actually the opposite. It gives real life examples of how the underdogs, the underprivileged, and unfortunate have actually persevered above all expectations. He begins with the famous, true story of a giant and a shepherd. David and Goliath: Underdogs, Misfits, and the Art of Battling Giants is a must read.
