The rumors are true...I am an outliner.
The truth is I need to see the plot naked and bare and without all the frills of, you know, good writing. Things like fully-formed sentences or descriptions that make sense...they only drag me down when I'm first embarking on a novel.
And for this, I have to thank my screenwriting background and film school, where I learned all about beats, character sheets, three-act structure and more craft commandments at whose ground I now worship.
