People loved their horses, too. But you don't keep riding your horse to work just because you love it.

I think frugality drives innovation, just like other constraints do. One of the only ways to get out of a tight box is to invent your way out.

If you only do things where you know the answer in advance, your company goes away.

But there's still so much you can do with technology to improve the customer experience. And that's the sense in which I believe it's still Day One, and that it's early in the day. If anything, the rate of change is accelerating.

The balance of power is shifting toward consumers and away from companies The right way to respond to this if you are a company is to put the vast majority of your energy, attention and dollars into building a great product or service and put a smaller amount into shouting about it, marketing it.

We innovate by starting with the customer and working backwards. That becomes the touchstone for how we invent.

The world is littered with corpses that predicted technology in a particular arena was done. If there's another gigantic step change out there, we don't yet know what it is.
