““Many fear this side of the door. We crave stability and certainty, so we keep both feet rooted in what we know, believing that if we repeat ourselves or repeat what is known to work, we will be safe. This feels like a rational view. Just as we know that the rule of law leads to healthier, more productive societies or that practice makes perfect or that the planets orbit the sun, we all need things that we can count on. But no matter how intensely we desire certainty, we should understand that whether because of our limits or randomness or future unknowable confluences of events, something will inevitably come, unbidden, through that door. Some of it will be uplifting and inspiring, and some of it will be disastrous.””
