FIRST DRAFT CRAZINESS

Help!  I’ve working on a new book and I've reached that stage where I'm within striking distance of the end – (actually, I’ve already written the ending), but I need to complete a few connecting threads.  Obviously, these connecting threads are the points in the story that I didn't want to write the first time through because they were too hard or too boring or too . . . I don’t know what.  But, now I HAVE to write them.  There is no escape.
Agony. 
Can’t I just skip them?
No.  Of course not.
So, here’s what happens.  I write a hundred words, okay maybe a hundred and fifty -- and then I hit a wall.  And, my poor battered brain is so starved for some pleasurable feeling, all it can think is CHOCOLATE  NOW!  So, I check the clock.  But, it turns out it's been less than an hour since my last chocolate break, so there's no way I can justify another one.  Not if these chocolate rewards are to have any meaning at all.
I go back to work.  And pretty soon, I’m checking the clock again.  And only ten minutes have passed this time.  I can’t believe it.  Surely it’s been longer than that.  But, no.  It hasn’t.   And I still have four more of these little threads to write.  And they really don’t add up to that much, not compared to a whole novel, which is what I would have if I would just buckle down and finish.  
I pretend to write another hundred words, but my brain is still fixated on chocolate.   FOR HEAVEN’S SAKES, GET ON WITH THE WORK, I tell myself. 
And if I’m really desperate, I might get up and play the three songs I know on the piano, which are really just beginner pieces, because I was a pathetic piano student, but they will have to do.  Or, maybe I play the dulcimer.  Or, when things are really grim, I clean the bathroom.  No.  not just clean.  I scour grout between tiles. 
 And three hours later, no connecting threads have been written.  Maybe the bathroom’s a little cleaner, but the day is nearly gone and what have I accomplished?
 Clearly the only answer is to get out of the house and go someplace where there is NOTHING ELSE TO DO BUT WRITE!
Ah… Better. 
Yes.  That’s two threads down.  Only a couple more to go.
And hey, the bathroom’s clean.  Bonus!  Not a bad day’s work.  But, can I tell you how much I prefer revision?  It’s much less fattening.  Of course, the bathroom tile doesn’t shine and dust tends to collect on the piano.
