Nobody knows everything.
No matter how much we learn, we're always operating with flawed models of the world.
But reality doesn't go easy on us.
Even the most understandable mistakes can be fatal. Lives can be torn apart by good people with good intentions.
How to account for this?
By accepting it as a fixed cost.
Potential is perishable, and we only have so much. Sometimes, doing nothing is the riskiest choice of all.
Smart mistakes beat stupid mistakes, but some mistakes beat no mistakes. And often, these errors are reversible.
Except when they aren't.
