In his new book, 10% Happier, ABC News anchor Dan Harris tells the story of how a skeptic became a meditator, and how the practice helped him better manage an extremely competitive career. One of the key developments in Dan's strange odyssey from avowed critic of all things touchy-feely to unlikely evangelist for meditation was an unusual friendship with Dr. Mark Epstein, the Buddhist psychiatrist and author. Through many years of regular lunches and dinners, Mark helped Dan see the value of mindfulness — and also its limits. During this evening event, the two will share the story of their friendship and its lessons.
