I need the structure, or an urge to the structure, a tickling vision, a hint or itch or organic flux to the structure (this is why I teach so many scaffolding-of-fiction based classes—we all have our biases) to begin the writing, to flow. What do you need? What do you need for the click to kick in (Brick: It’s like a switch, clickin’ off in my head. Turns the hot light off and the cool one on, and all of a sudden there’s peace.) ?
