How I create my plots is just remembering those great moments in my life. Some moments may be sad, some maybe happy, and some may be tragic, but when you take your emotions from those moments and put them on a piece of paper then almost every time you do so, your plot just unravels by itself. I could give you a perfect example of how this happened for me. When I was thinking of my second book, I couldn't get my plot down so I thought of the most tragic day in my life... The day I had to leave the person I loved the most. it was one of the most heart wrenching days in my life that to this day I still cry about. I took those emotions and I put them towards my second book and would have taken me days to make took me hours. So if you are having issues with your plot try using this method, you may find that it it really does work.
