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.

Most big technology companies are competitor focused. They see what others are doing, and then work to fast follow. In contrast, 90 to 95 percent of what we build in AWS is driven by what customers tell us they want.

Customers want to save money and time and have the broadest assortment of items, and we think that by bringing e-commerce and digital capabilities together with the stores, we can do things that a pure e-commerce player can't.

Long-term thinking levers our existing abilities and lets us do new things we couldn't otherwise contemplate. It supports the failure and iteration required for invention, and it frees us to pioneer in unexplored spaces. Seek instant gratification-or the elusive promise of it-and chances are you'll find a crowd there ahead of you.

If your customer base is aging with you, then eventually you are going to become obsolete or irrelevant. You need to be constantly figuring out who are your new customers and what are you doing to stay forever young.

One of the technology leaders, a few years ago, was visiting with me here and we were writing on the whiteboard and they stopped and turned around and looked at me and said, "Oh my God, you're going to win." And I said, "Yeah, but why?". "Now, tell me how".
