Lots of writers dawdle around when then write. Imagining what the next line might be or worse, what their Aunt Gerdie might say if she were ever to read that next line. This is the equivalent of trying to get from New York City to the crab nebula by car then stopping just across the Jersey line at the Vince Lambardi Service Area. You’ll never get there.     
      The proper way to do things is put all the critical voices in your head in cryogenic stasis for the next ten minutes or so, and set your hand warp speed writing whatever comes out of you hand until you finish filling both sides of the page. Once you’ve arrived at the end of the journey without quite realizing it is a great time to look back at the ‘exhaust fumes,’ your words, and see what you’ve got that might be worth revisiting. That’s where the good stuff is.

Often in our writing we strive for perfection, for completion, and yet perfection is boring. It is the oddities and imperfections that we remember in the end.

Stanislavsky says as much in this quote I found in David Mamet's "3 Uses of the Knife."

       "And there are plays—and books and songs and poems and dances—that are perhaps upsetting or intricate or unusual, that leave you unsure, but which you think about perhaps the next day, and perhaps for a week, and perhaps for the rest of your life.
