On CreativityOn Creativity

“Creativity is just connecting thingsCreativity is just connecting things. When you ask creative people how they did thi th f l littl iltdid something, they feel a little guilty because they didn’t really do it, they just saw something. It seemed obvious to them after a while. That’s because they ywere able to connect experiences they’ve had and synthesize new things ”had and synthesize new things.
