Stay curious, find comfort in being wrong and create a "challenge circle" of people who actively challenge your beliefs - these are all steps towards knowing what you don't know according to Adam Grant. And he argues in today's rapidly changing work environment questioning your beliefs, rethinking and even unlearning are key skills. Adam is an organisational psychologist and professor at The Wharton School of the University of Pennsylvania. His research focuses on generosity, motivation and meaningful work.  And I imagine that there are few senior managers who don’t have at least one of his New York Times best-selling books on their shelves. His new is book Think Again: The Power of Knowing What You Don't Know in which he argues "if knowledge is power, knowing what we don't know is wisdom". Producer: Maria Tickle
