You can't get the good ones and the fruitful interaction among the odd ones unless you welcome the terrible ones.

“If you are trying to be inventive and come up with lots of interesting new ideas, it's usually the worst thing in the world if someone comes along and starts being critical. Thus, the power of brainstorming: no one is allowed to criticize any idea or suggestion that is offered—no matter how stupid, impractical, or useless it seems. You can't get the good ones and the fruitful interaction among the odd ones unless you welcome the terrible ones.”
