Don't be cocky. Don't be flashy. There's always someone better than you.

I view my role more as trying to set up an environment where the personalities, creativity and individuality of all the different employees come out and can shine.

I think a much better use of time and resources is to really focus on your existing users or customers and figure out what changes can you make in the Web site, the service, the product, whatever, to get them to come back more often to generate that repeat business and once you kind of figure out that formula, then when you get new customers the whole thing just kind of grows exponentially.

If someone is self-aware, then they can always continue to grow. If they're not self-aware, I think it's harder for them to evolve or adapt beyond who they already are.

At Zappos, one of our core values is to Pursue Growth and Learning. In the lobby of our headquarters, we have a giving library where we give away books to employees and visitors that we think will help with their growth, both personally and professionally. I can't wait to add The Compound Effect to our library.

Instead of getting an iPad, I now use my iPhone with a giant magnifying glass attached to my face.

I made a list of the happiest periods of my life & I realized that none of them involve money.
