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

The ultimate definition of success is: you could lose everything that you have and truly be okay with it. Your happiness isn't based on external factors.

Zappos uses call center technology to track average call time per agent. But the goal isn't to reduce this average - it's more important that we make an emotional connection with the customer, rather than just quickly getting them off the phone.

Whatever you are thinking, think bigger.

Instead of getting an iPad, I now use my iPhone with a giant magnifying glass attached to my face.

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.

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