Last night: 5 pages, bringing the total to 59. The screenplay is at least half done.
And you know, I'm starting to see the shape of it - and where it's going from here. It's exhilarating.
Of course, now that I see the shape - the frame - I look back at what's already been written, and I see what doesn't fit. There are elements that I'll have to finesse into the frame, and elements I'll just have to saw off.
But that can wait. I'm going to finish the draft first, and revise later.
This not some profound insight on my part - it's a generally-acknowledged truth that you'll find in many books and courses on writing, especially screenwriting: Don't go back and revise until you're finished your first draft.
To try to move forward while revising on the go is the path of madness, or at least of endless fiddling (almost the same thing - ask Nero). Each change sends ripples throughout the draft, and trying to smooth out the ripples makes more ripples. Better and easier by far to finish, then look back on the work as a whole.
There's no point in trying to make your work fit into a frame that only has two sides.
