Want to see a grown writer roll his eyes into the back of his head, stick his fingers into his ears and start chanting "na na na na na" like a four-year-old? Easy, just start talking about structure. Things like outlines and guidelines and scene structure and anything that smacks of planning and non-creative activity that will stifle the flow of electric wow-ness.
This paradigm of belief is based on the misconception and confusion regarding creativity vs creation. Creativity is a force, an energy, and a chaos, which if guided through a filter of brainstorming often results in plots, ideas, characters and dramatic paradigms for a story. Creation, is the process of structure applied to the wild energies.
