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.

Happiness is really just about four things: perceived control, perceived progress, connectedness (number and depth of your relationships), and vision/meaning (being part of something bigger than yourself).

Our customers call and e-mail us to say that's how it feels when a Zappos box arrives. And that's how we view this company.

If I was going to go into an office I wanted it to be with people I would choose to be around even if we didn't have to work together and so that was one of the major reasons why I decided out of all the different companies we invested in to work with Zappos.

Be true to yourself. If you follow that principle, a lot of decisions are actually pretty easy.

Your brand is your culture.

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