on the brink

Brinks can be very high, also very slow. I'm on the brink of finishing - sort of finishing - my screenplay that i have been poking at for six months now. It's the poking that has turned out to be a problem.  I have so many bits and pieces,  additions and separate areas of consideration  that I am having trouble collating them and pitting them in order and getting some fair copy out of this mess.  'working back and forth between two computers doesn't help, either.   Why do I do this?

What else would I do?

Right now I can think of several things.

Blogs cross my mind but I can't focus, not right now.

And the Blue Jays are playing the Orioles.

I'll think about it tomorrow.
