Keep track of cool ideas or visuals you encounter having to do with plot, character, or setting.
When you have enough of these cool ideas, synthesize and combine them into a complete story. Connect all the pieces together.
Write a book guide listing the elements of your plot, character, and setting.
Where you see holes in your story or setting, generate new ideas to fill them.
Create a list of various subplots and capital P plots in your book. Figure out where you eventually want the plot to go and work backwards: “What needs to happen for this to occur?”
Once it’s all mapped out, write your novel straight through not stopping to edit or revise. If you decide you need to change something mid stream, write a note to yourself and then simply keep going forward as if you had already revised. You can come back during the revision process and make the necessary changes.
