I went to Princeton specifically to study physics.

We've done price elasticity studies, and the answer is always that we should raise prices. We don't do that, because we believe -- and we have to take this as an article of faith -- that by keeping our prices very, very low, we earn trust with customers over time, and that that actually does maximize free cash flow over the long term.

Market leadership can translate directly to higher revenue, higher profitability, greater capital velocity and correspondingly stronger returns on invested capital.

We're not competitor obsessed, we're customer obsessed. We start with the customer and we work backwards.

People who are right most of the time are people who change their minds often

We see our customers as invited guests to a party, and we are the hosts. It's our job every day to make every important aspect of the customer experience a little bit better.

We are our choices. Build yourself a great story.
