The people who build spacecraft to explore the solar system can do this job only if they don’t freak out when they’re in the Dark Room, that place where you know you have no solution to your problem. So you develop resilience in order to avoid panic.

You’re working hard to stay in calm mode when occasionally it’s appropriate to freak out and hit the alarm.
