Why is finishing so hard?

Okay.
So I am in fact in bad, bad, bad mood.
For absolutely no reason I might add.
I had a great day. Work worked, laundry done, nap, guitar, waxing poetic about the perfect man.
But I do have to finish something. Why oh why oh why does this have to be like walking over glass every time? I don’t even want to try and finish. What I want is to have another drink and play Vampire Wars until Glee is on TV.
Stupid, stupid, stupid. Because it isn’t what I really want. What I really want is to have this movie outline finished. But no, not the least of it. I want it to be finished in grand and pleasing fashion. However ya big schmoop, it can’t even be a bad outline if it ISN’T FINISHED!
Resistance. The knot of phlegm in my head that must be expelled each and every day in order to get writing done.
If you pray, please pray for me.
Cripes, now my glasses are dirty and I must arise and clean them. And get a glass of ice water. Heavy on the ice. And wash my face since I’ve been crying and it feels all sticky.
Then I have to resume the position, tell my self again that writing is joyful, god damn it. And finish.
