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).

Just figure out what your personal values are then just make those the corporate values.

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.

Your personal core values define who you are, and a company's core values ultimately define the company's character and brand. For individuals, character is destiny. For organizations, culture is destiny.

A bigger business is like a cruise ship: There are lots of amenities and you can go a lot further, but it's harder to turn quickly.

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.

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