I spent the majority of Sunday, from 8am to around 6pm, parked in my favorite armchair with my laptop, editing The Empire's Edge. I got through ALL of the crits I'd collected in the past two years on it and am now ready to print it out to go over again, looking for holes.
Why was that so tiring? I did nothing all day. LOL. I actually looked forward to today's editing work because it wasn't going to be so difficult.
