I think frugality drives innovation, just like other constraints do. One of the only ways to get out of a tight box is to invent your way out.

In the end, we are our choices.

If you do build a great experience, customers tell each other about that. Word of mouth is very powerful.

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.

If you never want to be criticized, for goodness sake don't do anything new.

I don't want to use my creative energy on somebody else's user interface.

If you want to be inventive, you have to be willing to fail.
