James Cary is good. Experienced, insightful, pragmatic, a good communicator— if you want to improve your screenwriting and enjoy that process along the way, this is the person you want to follow. Plus he's got a cool accent, so sign up for whatever online event he offers, just to hear him. (n.b.: he is in the UK, so translate his events to your time zone)
Russell is a personal friend but also happens to be the wisest, most forthcoming "lab rat" in the world of indie publishing. Whatever hot new thing comes along to help an author sell books, Russell will try it, track exactly what happens, and publish the results so that you and I need not suffer. He has mastered every aspect of the indie author life, and has written exhaustively about most of it. Be a paid subscriber and scroll through his vast archives... wow.
One of the best sources I've ever found concerning indie publication, publicity, marketing, and direct sales. If you want to find readers who will love your work, Monica is your "source of all knowledge." Become a paid subscriber and scroll through her archives. They are vast, and vastly valuable.
