The magic of generating new ideas
Coming up with something truly new is much, much harder than people give it credit for. We take the sun being the center of the universe for granted today, but it was an extremely non-obvious fact for the smartest people in the world for millenia. One of my math professors had a great take on the difficulty of injecting a new idea into the world: he said that the greatest mathematical achievement that anyone had ever made was not anything like calculus - it was the realization that there was something similar between five stones and five fish.
