I've been working hard on my plots. Changed the focus of the novel and honed it down to one central protagonist with a single main goal to provide some real drive to the story. Thanks to the great recommendation from my current writing teacher, Dennis Foley, I'm using beat sheets to help me outline better and more simply. Foley's Writing The First Novel class is great, by the way. Already into Week 5 of it - excited for even more insights awaiting me in the last half of the course.
Beat sheets are the outlining method used in Hollywood (where Foley started his writing career). Just write out each beat that's necessary for moving the plot forward, then go back over it and divide them into scenes/locations. So simple and so useful.
