Write the basic story BEFORE you edit. Never edit during the creative process. Editing come from a different part of your brain. Concentrate on your story - the entire story not just one chapter. Don't worry about spelling or grammar. Get the basic story straight first. Then go back and fill in the details. Then edit.
That's probably the best advice... just do it.
I'll second this one. You have to give yourself permission to write that shitty first draft (and 2nd draft and 3rd...)and worry about fixing it up later. Constant editing as you write will kill you and you'll wind up never finishing anything.
While the constant tinkering is most likely your problem, it's also possible that you're someone who needs to outline. Some people can just start writing and wind up where they need to be, but 99 writers out of a 100 will end up trapped in a ravine. The level of detail is up to you, but it's easier to drive when you know where you're going.
My final bit of semi-useless advice is to stick it in a drawer for the next 3 months to a year and start writing something else. Sometimes you just need a vacation from your story.
Time is winding down. Use the moments remaining with grace.
For all that we have failed to accomplish, there must be a letting go. Find joy and beauty in this moment and this day.
For tomorrow and the day after are tenuous concepts.
Rejoice in this dawn, if it arrives, and look for the peace that permeates all creation.
