There are many paths to the perfect plot. You can take the Zen road and write your story in a state of flow. Think of it as letting the story reveal itself, associative writing, etc. At the other end of the spectrum, the events of the story can be planned down to very last. In this vein, one can start with an outline on a piece of ruled paper.The sparseness or detail, and style of the outline is determined by the author. Each scene can be detailed on note cards, then written full length and strung together to form the story. Very often, the plot that begins a story can change with every revision. The key is selecting the course of events, steps to follow, which will end in creating your perfect plot.
