"Creative insight of any type — be it business strategy, an ad campaign, or computer code — requires cognitive space to emerge."

Ann Patchett: “It used to be a novel lived very nicely in my head as a constant companion,” she explains. “As time goes on and I now have this other thing which is my career, and all the things that people want me to do, that is very distracting to day dreaming and working in your head.”
