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).

Stop chasing the money and start chasing the passion.

The brand is just a lagging indicator of a company's culture.

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.

Ask yourself: would you be comfortable printing everything your employees, customers & partners have to say about your culture?

A great brand is a story that never stops unfolding.

I think maybe 50 years ago people and businesses felt like they had to choose between maximizing profits and making customers happy or making employees happy, and I think we're actually living in a special time where everyone's hyperconnected, whether through Twitter or blogs and so on. Information travels so quickly that it's actually possible to have it all, to make customers happy through customer service, to make employees happy through strong company cultures, and have that actually drive growth and profits.
