Этот действительно базовый принцип успешного написания чего-либо был предложен писательницей Ann Lamott в книжке «Bird by bird»:

«The first draft is the child's draft, where you let it all pour out and then let it romp all over the place, knowing that no one is going to see it and that you can shape it later.» Let your ideas flow the first time you sit down to write that article or story. It's only when you write those terrible first drafts will you be able to produce really, really great stories.источник
