Writing Process

Finishing my paper on Williamson's "Knowledge and Its Limits" is going torturously.  I have always done this and I think its a pattern I need to break out of.  Rather than just writing then going back and editting, I tend to belabor every single point as I'm writing.  So, if I can't quite make my mind up I'll just do something else for a bit.  I can't get myself to move on from a point then come back to it later.  I guess its an odd kind of perfectionism or something.  Presently it's driving me batty.  I've had this paper pretty well worked out in my head for weeks.  I just keep ruminating the same points over and over.  Then I sit down to write and can't spit them out.  Bahhhh.  Tomorrow I must finish.
