We are pushed toward maximizing efficiency in a way that leaves no room for error

Exploiting an opportunity to its full extent has a terrible side effect: When all opportunity is exploited, and there is no room for error, any system exposed to volatility and accident will eventually break.

For example, people strive for efficient lives where no hour is wasted. But when no hour is wasted you have no time to wander, explore or let your thoughts run free – which can be some of the most productive forms of thought.

The paradox: maximum efficiency is essential for surviving the short run, while room for error is essential to survival in the long run.
