As an entrepreneur, I try to push the limits. Pedal to the metal.

Uber is efficiency with elegance on top. That’s why I buy an iPhone instead of an average cell phone, why I go to a nice restaurant and pay a little bit more. It’s for the experience.

Our whole goal is to drive the cost of taking an Uber BELOW the cost of owning a car.

There has to be a large number of people and routes that are lined up together. One part is liquidity and the other part is product - there's a lot that can go wrong.

We like to think of Uber as the cross between lifestyle and logistics, where lifestyle is what you want and logistics is how you get it there.

You're asking somebody who has a wife and is really happily married, 'So, what's your next wife going to be like?' And I'm like, 'What?'

If you bring that scrappy fierceness with you it works until you get big, when really pushing all the way really feels uncomfortable...When you're the little guy that's lauded, that's heroic.
