We miss out on wisdom if we’re too narrow...Specialists become so narrow that they actually start developing worse judgment about the world as they accumulate knowledge...Breadth of training predicts breadth of transfer. Transfer is your ability to take knowledge and skills and apply them to a problem or situation you have not seen before. And your ability to do that is predicted by the variety of situations you’ve faced...As you get more variety, you’re forced to form these broader conceptual models (in the classroom setting called “making connections” knowledge), which you can then wield flexibly in new situations.      - David Epstein
