"If fear hinders us even in grade school, no wonder it takes such discipline--some people even call it a practice--to turn off that inner critic in adulthood and return to a place of openness. In Korean Zen, the belief that it is good to branch out beyond what we already know is expressed in a phrase that means, literally, "not know mind." To have a "not know mind" is a goal of creative people. It means you are open to the new, just as children are. Similarly, in Japanese Zen, that idea of not being constrained by what we already know is called "beginner's mind." And people practice for years to recapture and keep ahold of it."
