The rhythm of a writer’s day

“What is the rhythm of a writer’s day? First, you enter your imagined world. As characters speak and act, you write. What’s the next thing you do? You step out of your fantasy and read what you’ve written. And what do you do as you read? You analyze. “Is it good? Does it work? Why not? Should I cut? Add? Reorder?” You write, you read; create, critique; impulse, logic; right brain, left brain; re-imagine, rewrite. And the quality of your rewriting, the possibility of perfection, depends on a command of the craft that guides you to correct imperfection. An artist is never at the mercy of the whims of impulse; he willfully exercises his craft to create harmonies of instinct and idea.”
Robert McKee

Why master the craft

“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.”
