One of the things we don't do very well at Amazon is a me-too product offering. So when I look at physical retail stores, it's very well served, the people who operate physical retail stores are very good at it...the question we would always have before we would embark on such a thing is: What's the idea? What would we do that would be different? How would it be better? We don't want to just do things because we can do them...we don't want to be redundant.

If we can arrange things in such a way that our interests are aligned with our customers, then in the long term that will work out really well for customers and it will work out really well for Amazon.

Our judgment is that relentlessly returning efficiency improvements and scale economies to customers in the form of lower prices creates a virtuous cycle that leads over the long term to a much larger dollar amount of free cash flow, and thereby to a much more valuable Amazon.com.

If everything you do needs to work on a three-year time horizon, then you're competing against a lot of people. But if you're willingto invest on a seven-year time horizon, you're now competing against a fraction of those people... Just by lengthening the time horizon, you can engage in endeavors that you could never otherwise pursue. At Amazon we like things to work in five to seven years. We're willing to plant seeds, let them grow-and we're very stubborn. We say we're stubborn on vision and flexible on details.

Starter pack of essentials for Day 1 defense: customer obsession, a skeptical view of proxies, the eager adoption of external trends, andhigh-velocity decision making.

What characteristics do I look for when hiring somebody? That's one of the questions I ask when interviewing. I want to know what kind of people they would hire.
