Let's put it this way: if you are a novelist, I think you start out with a 20 word idea, and you work at it and you wind up with a 200,000 word novel. We, picture-book people, or at least I, start out with 200,000 words and I reduce it to 20
Simple is often erroneously mistaken for easy. "Easy" means "to be at hand", "to be approachable". "Simple" is the opposite of "complex" which means "being intertwined", "being tied together". Simple != easy
