Plots, Subplots & Outlines
I know some people don't outline and I respect every one of them. That said, I need to tell my story first as an outline or a sloppy synopsis. I find plot holes. I find places were I've painted myself into a corner. I never go off on a tangent and have to delete thousands of words. I can easily see the tension build and if it isn't, I'm able to fix it early.
Basically I'm saying I'm lazy.
