My friend and colleague Bruce Rosenstein is a prolific writer and editor. He’s managing editor of Leader to Leader, author of the wonderful Living in More Than One World: How Peter Drucker’s Wisdom Can Inspire and Transform Your Life (Berrett-Koehler, 2009), and wrote for USA TODAY for more than two decades. Bruce knows more than most about the late Peter Drucker, the most acclaimed management thinker of all time.

Bruce spent many hours with Drucker, and is both a student and scholar of “the Drucker way.” I’ve read everything Drucker ever wrote, and if there’s one thing I took from his collected works, it’s that he was always ahead of his time. He was on Main Street long before the parade arrived. I would challenge anyone to point to a business or management idea that can’t be traced to Drucker within a few degrees of separation.
