"Brainstorming seems like an ideal technique, a feel-good way to boost productivity. But there is a problem with brainstorming. It doesn’t work."

"Solitude, as Cain says, is a key to creativity. Darwin took long walks in the woods and turned down dinner invitations, Dr. Seuss wrote alone, and was afraid of meeting the kids who read his books for fear they would be disappointed at how quiet he was. Steve Wozniak claimed he never would have become such an expert if he left the house. Of course, collaboration is good (witness Woz and Steve Jobs), but there is a transcendent power of solitude."

"End the madness of constant group-work." (The audience applauds.) Offices need chatty conversations, and great spaces to make serendipitous interactions. But we need much more privacy, and more autonomy. The same is true - more true - for schools. Yes, teach kids to work together, but also how to work alone."
