I have seen this pattern in many scripts, and Have used it myself. This pattern is as follows:
I want to …. right now.
I need to …. right now.
I am going to …. right now.
I think this is a good close off to many scripts because it denotes, the motivation, and call to action of doing whatever the script is about. It seems like it would also instill a sense of urgency regarding the scripts topic as well.
