One of the things that I hope will distinguish Amazon.com is that we continue to be a company that defies easy analogy. This requires a lot of innovation, and innovation requires a lot of random walk.

My view is there's no bad time to innovate.

We innovate by starting with the customer and working backwards. That becomes the touchstone for how we invent.

As we transition from one screen to multiscreens, Google has enormous opportunities to innovate and drive ever higher monetization. Just like Search in 2000.

To turn really interesting ideas and fledgling technologies into a company that can continue to innovate for years, it requires a lot of disciplines.

To innovate, you need a spirit of inquiry.
