Embedded below is a great 4 minute video of Tom Peters on the definition of leadership. The essence is captured by Robert Altman’s lifetime achievement Oscar acceptance speech: "The director allows an actor to become more than they’ve ever dreamed of being."
Peters also says that people often ask him about the key to leadership in the 21st century. He says "nothing has changed." The key to leadership in the 21st century B.C. is the same as it is in the 21st century A.D. Yes!
