My plans nearly always take longer than expected to come together. The pace I set for myself for a few weeks there was not something I could sustain. I decided early on that I wanted to do a deeper edit than just fixing a few typos, but I was still trying to get 4 or 5 chapters done a week because I so badly wanted to get this fresh version of the book out for readers.
I guess I needed a reminder that I have always needed to take my time and go at my own pace. As much as I want to get these books through final edits and out into the world, I'm trying to do what's best for the series for the years to come. And that requires me to work at my own speed, which has always been slower than most of my peers.
Go at your own pace.
