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

Help inspire people to realize they are capable of changing the world.

Businesses often forget about the culture, and ultimately, they suffer for it because you can't deliver good service from unhappy employees.

Hopefully 10 years from now people won't even realize we started out selling shoes. They will just think about Zappos as a place to get the best customer service.

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).

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.

Every employee can affect your company's brand, not just the front-line employees that are paid to talk to your customers.
