Bezos had imbibed Walton’s book thoroughly and wove the Walmart founder’s credo about frugality and a “bias for action” into the cultural fabric of Amazon. In the copy he brought to Kathryn Dalzell, he had underlined one particular passage in which Walton described borrowing the best ideas of his competitors. Bezos’s point was that every company in retail stands on the shoulders of the giants that came before it.
It's interesting to learn where Bezos got a lot of his leadership ideas from. When you are inside Amazon the leadership principles are like air, its all around you but you don't think about where they came from.
