Never stop writing at the end of a chapter.
I managed to put a cap on the chapter I have been struggling with for the past few days, and am now staring at a blank page with 'Chapter Seven' written across the top. Because of the way I restructured and broke up Chapter Six, this will be entirely new; no editing of what is already there.
I'm finding the short (one hour each) bits of time I have not adequate for such a daunting undertaking and would love a chance to sit for about four hours working this out.
Just a few months ago I was struggling to fill 5 hours a week, and now I'm finding that 15 isn't enough.
