Play is the essence of learning and creativity. The phenomenon of censoring and thresholding – sensible when one has attained a level of expertise in a subject – gets in the way of learning in a new domain. Why children learn faster is that going into a new activity, they have no threshold. They draw and write whatever they think of, while an adult throws away ten germs of ideas before they write a single word. Sometimes, the best way to get better is by doing lots.
