I have up until chapter 24 outlined and by the time I get there I'll know for sure what I want to happen in the chapters that follow it. I want to keep trying to do a chapter a day. This won't always be easy, or possible, but I would love to keep this momentum going. When this draft is done, I'm going to let it sit until December. I'll spend the Christmas month doing revisions so it can go out to my spectacular beta readers in January. This is my plan and I'm going to do my best to stick to it.
So go out and try things. Fail, learn, and explore. The only way you can figure out how much you can accomplish is to set goals. Sometimes we expect too much and set the bar too high, and that's fine too. We have to learn where our limits are so we can push beyond them.
