When I was in grade school, I learned about plots. I was given a diagram that looked something like this:
There are multiple problems with this idea, when I look back on it now. For one thing, the diagram is an oversimplification. Many stories have plots that include these plot elements, but they aren't necessarily well-defined, or in this particular order, or occurring only once in the story.
Another problem, which is more notable to me, is that this plot structure is just one aspect of creative writing. I was taught to write stories like this, and I found it to be constraining and unintuitive. As soon as I let go of the idea of plots, specifically formulaic ones, I had this realization of "I can take a story wherever I want." It was liberating. And yet it seems so obvious.
I know plots can have different forms, but now I often reject the idea of plots as applied to my own work, because I associate them with this idea that fiction should be a certain way. I write Think Before You Think, and I never say that it has a plot - to me it's just a somewhat spontaneous progression of events, and if a plot somehow happens to it, then sobeit.
