Find a story you admire, one with a tight, linear structure. Stories by Flannery O'Connor or Tobias Wolff would be good choices. Read the story slowly and thoroughly five times, so that you are emotionally detached from the narrative, so that you are able to recognize every sentence as a moving part that contributes to the overall design. Then read it again, for a sixth time, with a notebook next to you. Chart the architecture of the story. Indicate a new paragraph with a dotted line running across the page. Separate every instance of white space with a bold line. Track each paragraph, noting every relevant element. Example: Opens with a description of setting that clues us in to the mood of despair. Character A introduced with a line of dialogue that reveals his selfishness. And so on. When you finish, write your own story that bears no resemblance to the original except in its design. Paste new flesh on an old skeleton. For canonical examples of this, compare "Mexico" by Rick Bass to "The Prophet From Jupiter" by Tony Early or "The Lady With the Pet Dog" by Anton Chekhov to "The Man With the Lapdog" by Beth Lordan.
