Gallup Senior Scientist Arthur C. Brooks, professor of the Practice of Public Leadership at the Harvard Kennedy School, rejoins the podcast to discuss his latest book, From Strength to Strength. Do ambitious strivers suffer down the line, in terms of their happiness? Is there something we can gain from our moments of suffering -- and what can we learn from our weaknesses? Why do we need friends -- and what is the difference between real friends and “deal friends”? Brooks discusses all of this and more.
