If you're going to succeed, you need a vision, one that's affordable, practical, and fills a customer need. Then, go for it. Don't worry too much about the details. Don't second-guess your creativity. Avoid overanalyzing the new project's potential. Most importantly, don't strategize about the long term too much.

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.

To be clear, we take these financial outputs seriously, but we believe that focusing our energy on the controllable inputs to our business is the most effective way to maximize financial outputs over time.

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.

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.

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 actually does maximize free cash flow over the long term.
