Prepared but not paranoid
Things don’t happen as often as it feels like they happen. Most of the time, when it seems like something is going to happen, instead, nothing happens. Or at least something totally different happens. You might imagine a thousand different disasters a day, but it’s highly unlikely any of them will actually take place in the real world.
But don’t confuse that with the idea that nothing ever happens. Most hypothetical disasters never happen, but that doesn’t mean there are no disasters. Be prepared without being paranoid.
