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

Success is getting to a point where you'd be truly OK with losing everything you have and starting over.

Have fun. The game is a lot more enjoyable when you're trying to do more than just make money.

Our belief is that if you get the culture right, most of the other stuff, like great customer service, or building a great long-term brand or empowering passionate employees and customers, will happen on its own.

I'd rather spend money on things that improve the customer experience than on marketing.

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.
