I think competition can make people stronger at whatever it is they're competing on. If we're competing in some athletic event for competitive swimmers, really intensely competing, it's likely that both of us will become better, but it's also quite possible we'll lose sight of what's truly valuable.

I really admire Airbnb as a pioneer of the sharing economy and for building community. They've found an elegant way to help hosts make more money and for guests to have authentic experiences. It brings those people together in a unique way.
