Beginning becomes less intimidating when you name what is allowed to be rough.

Much of the weight at the start comes from an unspoken demand that everything be decent at once. When you have not said which parts are allowed to be ugly, all of them feel required, and so nothing begins. Naming the rough parts in advance turns a vague standard into a small and workable one, and gives your attention a single place to be careful.

Before your next session, write one line saying what does not have to be good yet: the wording, the order, the proportions, the finish, whichever applies. Then work under that permission and judge only the part you kept.
