Listen to all nine operating principles narrated, start to finish. Hear the concepts on the go, in the car, at the gym, doing the dishes, without carving out time to sit down and digest them. Same guide, now in your ears for the price of a coffee.

The guide shows you how the great companies got BUILT. This shows you how the great families KEPT it. The advanced operating principles the world's wealthiest families used to hold their fortunes for generations. How Walton handed Walmart to his kids before it was worth a dime. How the du Ponts put one seat in charge of the whole board. Not in the main nine. Add it once, here, or pay full price later.
