Every Success Story Is Assembled Backwards
Narratives are built from the ending, which is why they always seem to fit.
Nobody tells the story of their life forwards. They start from where they ended up and work back, selecting the moments that lead there. The chance meeting becomes a turning point. The offhand decision becomes a bold gamble on oneself. The three years that went nowhere become a period of quiet preparation. None of this is dishonest. It is how memory works. But the effect is a narrative in which everything points at the destination, because anything that did not point at the destination was left on the floor during the telling.
Watch what this does to causation. Once a chain has been assembled, each link seems to require the next, and the whole thing acquires an air of inevitability that it never possessed at the time. Ask the same person what they thought would happen at any given step and the answer is usually vaguer and more anxious than the polished account suggests. The confidence in the story was added later, in the edit.
You can use this deliberately. When you read or hear an account of how something turned out, try to reconstruct the moment before each supposed turning point, when nobody knew which way it would fall. Ask what else could have happened from there, and how the story would have been told then. Doing this does not make you a killjoy about other people's achievements. It makes you far better at judging which parts of a story you could actually reuse.
