While I like the punchy title, I'd suggest the often invisible role of preliminary work IS a part of being creative. In music it's "demos," in art it's "sketches," in writing it's "drafts," etc. I write in my book, Creative Doing:

> This stage is far too early to demand perfection; it’s best to keep expectations low, to refrain from self-criticism, and to support psychological safety (the feeling that it’s okay to make mistakes) to allow every single detail of the idea to flow out.

It's related to the original post's mention of scarcity, and how "the path to writing a great song really is through hundreds of mediocre songs." The most reliable way to good work is to allow it to emerge through a lot of preliminary work (e.g., lots of drafts, demos, and sketches).
