The biggest thing I do to pull it all together is to write a pretty extensive outline before I start the first draft. Otherwise I go off on tangents and just meander along, taking the scenic route to get where I want to go.
I don’t let it sit either before I start revisions. I have a list of words and phrases I tend to overuse, and the first thing I do is a search for each of those. Then I start at the beginning and go through every sentence, checking that it’s written the most effective way, fiddling with word choice, etc. I make sure each paragraph is cohesive and logical, rearrange as necessary. I also make sure each sentence and para is needed, advancing the story in some way, otherwise it gets cut.
Same thing on scene and chapter level. I pay particular attention to dialog and action scenes. After I’ve gone through the whole thing using track changes, I go back and either accept or reject the changes. Sometimes I find more things that need to be fixed. The goal is to make one more pass, just reading, to make sure it’s the way I want it.
I write the cleanest first draft I possibly can, cutting down on the spelling and grammar fixes needed, so I can concentrate on the bigger picture stuff later.
