I'll conclude my series on screenplay writing with a quote from How to Write a Movie in 21 Days. The quote is about quitting. Yes, quitting. Sounds like such a downer, right? Actually, it's surprisingly inspirational:
Definition of a winner--If the goal doesn't work, change it and win.
This is just a movie. It is not you. You will live whether or not you finish the script. You just think you won't...Make a decision now. Can you go on with the script? Can you find the way to move forward? If you can't, then let it go. Letting it go is also forward movement.
If you don't want to do something, then acknowledge that you don't want to. Don't pretend to try. Use that energy to do what you do want to do.
Which is exactly what I'm going to do. I have a half-finished novel that needs finishing, and a finished novel that needs to go on a quest to find a publisher.
