If you put 1000 people in barrels, and push them into the Niagara river, and they go over the falls, about 100 of them will survive. If you put those 100 people into new barrels, and push them over Niagara Falls again, about 10 of them will survive.
And those 10 people will all write books explaining how their specific backgrounds, life choices, etc, were the reason they survived.
Most people are control freaks. They do not like to accommodate randomness in their lives. It doesn’t “fit the narrative”
