Former Ambassador to the United Kingdom and Sweden Matthew Barzun joins Zibby to talk about his latest book, The Power of Giving Away Power, and how the best leaders are often the ones who don't lord their power over others. Matthew shares how his experience with the 2008 Obama presidential campaign and his interactions with Queen Elizabeth sparked his research, as well as how their leadership style often inspires their supporters to be more willing to volunteer than accept payment for their efforts.
