Uber is a $3.5 billion lesson in building for how the world *should* work instead of optimizing for how the world *does* work

Opportunity lives at the intersection of what people need tomorrow and can be just barely built today.

If you're in your early 20s and you're hanging out with a bunch of other people in their early 20s, nobody has a sense of the kinds of problems that real 'workers' run into every day. They're running into a completely different set of problems like 'what's the party going on right now that I should be going to?

Tip: Take the stodgiest, oldest, slowest moving industry you can find. And build amazing software for it.

You want to find the really crazy but still somewhat reasonable outliers within the customer ecosystem.

You'll learn more in a day talking to customers than a week of brainstorming, a month of watching competitors, or a year of market research.

Why we do what we do: that moment when you get to see the future on your computer screen before the rest of the world.
