Someone I know who travels a lot says that you only learn how to make good use of time in airports after you've had the experience of missing a few flights. You get an understanding of the time costs of failing and can make better decisions because of it.

I think money is the same way. People think a lot about constantly growing, and desperately try to avoid losses, but every time I lose a larger amount I find that I become more confident and more effective.

By that definition Mark Zuckerberg is having a great week.
