I use bodily similes not mechanical ones, walking, running, dancing, not driving fast or slow in a car or flying in a plane, because I think art depends on rhythms, and body rhythms are what writers use. Mechanical rhythms, non-rhythmic movement like in a car or plane, may be used successfully in mechanical arts, like the movies. But writing, whatever its medium, is made of words, and words are bodily, made with the body and the breath, received by the body, felt with the body, and the rhythms of words are bodily rhythms.
"A story has a beginning, a middle, and an end:" This comes from Aristotle, and it splendidly describes a great many stories from the European narrative tradition, but it doesn't describe all stories. It's a recipe for steak, it's not a recipe for tamales. The three-part division is typically European, and I would say that it's also typically European in putting emphasis on the end — on where the story goes, what you get to.
