Here's what I learned (and what I'm still grappling with):
1. It is possible to overthink until there's nothing left.
Afterward, when I got my sanity back, I checked the older version in my Kindle and found the paragraphs I'd sliced weren't all that bad. I may have to flesh things back up again. Lesson: Breaks are necessary. When you start editing yourself into corners, stop!
2. I should just set a timer.
Ha! Timer, you say. I ignored said timer, determined (very irrationally) to finish. I need to find a more compelling reason to stop when I need to. Lesson: I can't do everything all at once, and sometimes make things worse when trying. Space allows for necessary problem-solving.
3. But what if I forget to make space in the thick of it all?
If my mind won't tell me, my body will. My stomach growled at me for the last hour, and my eyes were so tired they were about to fall out. Lesson: Even if you're in the middle of a sentence, it's necessary to stop when your body is breaking. See #1.
4. My body and mind are linked. In the worst possible way.
Not only was my body in serious need of food, I was near the point of tears. My hyperfocused state wound me up like an overused guitar string. Lesson: Being emotionally frayed will not help your story. Or sentences. Or anything.
5. Rinse before repeating.
One of the main reasons I'm writing this post is I'm due for another editing bender this evening. Here's hoping I can remember all this before my mind gets into the zone of ignoring everything except the words on the page. Lesson: Remind yourself of what's important before you actually sit down to write.
So--is this an affliction shared by
