I spent last night editing a short story for submission this weekend. The feedback I got from my critique group was useful but to implement it I have to rip out pages and rewrite them.
The re-written pages felt false to me so I'm going to try to start again tonight. I'm almost tempted to send it out as it was, barring some line edits that my helpful fellow writer's found.
When I start tinkering with structure I find it causes a cascade of other changes that ends up altering the story's pacing. That landslide can bury character moments, world building...a host of things.
