Right now I'm staring at two fairly solid treatments for feature films I have yet to write. I have spent a fair amount of time refining them and working on them because like any real writer, I procrastinate actually writing the script until the last possible moment.
I have decided that I'm going to force myself to write at least five pages a day until I finish the first draft of one of them. In the past, this has proven successful, as I'll usually get on a roll, finish the first act in two days, sew up the second act within a week, and then take five days or so to get the third act done.
That's when I'm writing consistently. When my schedule is broken up by work and other obligations, I find it difficult to get the momentum going and the full process takes a bit longer.
So what's your method for kicking yourself in the ass?
