Without craft, the best a writer can do is snatch the first idea off the top of his head, then sit helpless in front of his own work, unable to answer the dreaded questions: Is it good? Or is it sewage? If sewage, what do I do? The conscious mind, fixated on these terrible questions, blocks the subconscious. But when the conscious mind is put to work on the objective task of executing the craft, the spontaneous surfaces. Mastery of craft frees the subconscious.
