a plot to conquer writer's block (hopefully)

I have noticed more and more how much I am doing the writer's block thing right now. I haven't gotten a lot of new stuff written in a while - I have been coasting on what I wrote with the last bout of good writing. So my plot for now is to work my way back to being able to do another good bout of writing. It feels like it is time to get the vehicle of my writing serviced - tune up type stuff. So I have printed out the rough draft so far - all of it - 116 pages single-spaced. I am reading through it right now and trying to pick out discrepancies and things that need to be fixed. I am not sure how many times I will need to read through it. Maybe this will be partly getting things in my memory correctly that I have written before. When I feel fairly confident that I have things straight there, I want to go through and make more of a plan of how I am going to work from what I have towards the rest of the story line. I want to make sure I keep myself pointed in the right direction. My goal is to get back to my daily goal of getting 2,500 words a day written. One thing I need to figure out is how to set a goal like that for editing and reviewing purposes. I am not sure if it would work better to think in terms of time spent - like setting a timer - or pages reviewed and edited. I am leaning towards the timer because it is less biased. There will be some pages that won't need more than just a quick read through, while others will need a lot more attention. So measuring my edit and review efforts with a timer seems like a better way to do it. For now I will review how much time I spend each day editing and reviewing, and go from there in deciding how much counts as a worthy goal for each day.
