'All advice is autobiographical'. We can only see the world from the perspective of the life we have lived. When we act, no matter how much homework we have done first, our conviction that we are right will always be partially based on overconfidence. The world isn't made up of clear choices between one and zero. The fuzziness, uncertainty and creativity allows us to make decisions rather than being stuck. The stories we tell ourselves help us act. When we share our learning, we are sharing our story. It won't be the same story for the listener. If the advice is a good story, perhaps they will assimilate some of the characters and plot twists.
