We've done price elasticity studies, and the answer is always that we should raise prices. We don't do that, because we believe -- and we have to take this as an article of faith -- that by keeping our prices very, very low, we earn trust with customers over time, and that that actually does maximize free cash flow over the long term.

I think one of the things people don't understand is we can build more shareholder value by lowering product prices than we can by trying to raise margins. It's a more patient approach, but we think it leads to a stronger, healthier company. It also serves customers much, much better.

Invention requires a long-term willingness to be misunderstood.

I like to be counted on.

If you can't feed a team with two pizzas, it's too large.

We are our choices. Build yourself a great story.

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 willing to invest on a seven-year time horizon, you’re now competing against a fraction of those people, because very few companies are willing to do that. Just by lengthening the time horizon, you can engage in endeavours 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.
