The Greek poet Archilochus wrote that "the fox knows many things, but the hedgehog knows one big thing." This week, we'll use the metaphor of the fox and the hedgehog as a way to understand the differences between tacticians and big-picture thinkers. We'll explore the story of a pioneering surgeon whose hedgehog tendencies led him to great triumphs, and a heartbreaking tragedy. This episode first aired in May 2017.
