Last Friday, during my first weekend residency at the Presidio Graduate School’s executive MBA program, I went for a walk with Peter Warshall. We walked in a small group through the Presidio, stopping every few minutes to look at the land, the trees, the animals. We started in a spot I have passed literally hundreds of times – an intersection near my former gym, down from my (green) dry cleaner and on the way to the swimming pool where my kids have lessons every Saturday afternoon.
