You're on a road trip with an old man and a younger one.

Business stories are told. Wisdom is revealed. A new perspective emerges. Companies like Costco and Kodak, General Motors and Walmart provide color and texture as they appear on the horizon and in the rearview mirror. Real companies. Real decisions. Real outcomes. Jeff Bezos and Amazon give this road trip its rhythm as the four pillars of their success are made plain. It's a wonderful success, easily repeated, even by a lemonade stand. But only if you understand the importance of the marshmallow.
