From Garr Reynolds: Now 73, Dr. Cosby may not be on the radar screens of a much younger generation, but ask any successful comedian working today — young or old — and they will tell you that Bill Cosby is the Obi-Wan Kenobi of comedy. What makes Bill Cosby one of the most compelling entertains of our time is his ability to connect with people and deliver his messages naturally in the form of story. He’s the master storyteller. He does so well what most leaders and presenters of all kinds should do: tell real stories from your own life in a way that is relevant and engaging to your audience. If more people could just remember that great speeches or presentations leverage the power of the speaker’s own stories, we could rid the world of a good deal of boring speeches overnight. Watch Bill Cosby’s keynote address at Carnegie Mellon University’s 2007 commencement ceremony below.
