Space I can recover. Time, never.

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.

The purpose of art is to stop time.

Strategy is all very well, but it pays to give thought from time to time to the results.

The secret of great battles consists in knowing how to deploy and concentrate at the right time.
