Editing is a killer of a process. I try to do some minor edits as I write (mostly to correct spelling errors) and then I try not to reread what I’ve just written for at least a whole day. That way, when I come back to edit, I have a better idea if the the sentence structure flows well. Or I’m able to see that I used the exact same descriptor in the prior paragraph.
Letting my brain just do it’s thing with writing instead of worrying about editing also helps me write faster. It’s about getting the idea out onto paper (ahem word doc) and then I can focus on editing later.
When I edit, I try to do a “general edit” of sorts, going over the entire chunk of work (a whole chapter, for instance), catching minor issues, then taking note of larger problems to work on a little more specifically. If I have a dialogue heavy scene but I needed to get it out of my head quickly, I might use the word “said” for the entire scene, so when I come back to edit, I’ll wait til round 2 of editing to focus on better descriptors to make sure the tone is coming across properly (“she said” turns into “she gasped, leaning away”). Then, when I’m done with those specific, larger edits, I’ll reread the entire section and see if it still flows and makes sense. If you’re concerned about it still, wait another day to look at it again.
I used to write a scene or a page and then sit there and edit it to death. So, now I have a strict, no-peeking policy as I write. It’s really helped push me to actually get more words out. But that meant I also had to refine my editing style, as well. There’s a reason why most authors have a separate person be their editor. There are some hacks, depending on what you’re hung up on, though. You can always put a few paragraphs into google translate (just English —> English) and have it “read” your writing out loud. It’s a lot easier to hear grammar or sentence structure mistakes because, when we read, our brain has a tendency to skim over simple mistakes. If there’s a real, but incorrect, word, your brain isn’t always going to catch it, because you know what the word is supposed to be, but it’s not misspelled, etc.
Anyway, sorry for rambling. Hopefully some of that was helpful?? Or, if not, at least know you’re not the only one that gets hung up on editing.
