A gentleman by the name of Matthew Jockers "did some distance similarity metric calculations and machine clustering" to determine how many different kinds of basic plot structures exist in the world of storytelling. 90% of the time when he ran the test, the answer was that there are six different plot structures, and 10% of the time, the answer was seven. Either result suggests that we are all drawing from the same plot designs over and over again.
These results beg the question: how are we coming up with so many different variations of the same plots? The answer is fairly clear. It's the amount of "you" that goes into the story you're writing. You have a style. You may not even know what your style is, but you do have one. I've suggested before that it's important that you be able to identify what that style is. It will give you more confidence as a writer, and it will give you a less cluttered path to plotting your next story.
In a monthly workshop I attend, the one question that is asked of every writer after reading their material is "What makes today different than any other day in your story?" The same can be asked when trying to define your style. What makes your story different from the other stories that share the same plot? Is it your choice of character? Is it your choice of narrator? Is it your choice of setting? What constant theme pops up in everything you write and sets you apart? What is the "you" in your writing?
