I've written 24K words in the new version to match the 24K words in the original. (Which under normal circumstances 48K would be 2/3rds a first draft of a full book.)
There are somewhere around 5 or 6 chapters left to write to catch up to the timeline of the first draft, so I've obviously fleshed out the second version by at least that much. This is even before combining the two versions which I'm sure will add ten to twenty percent to the total.
But it is really hard to motivate myself each day to write something I've already written. And getting harder. So far, I've managed to do it for 12 days. I need to keep it up for 5 or 6 more days, maybe more.
I shall do it out of general principles. I shall!!
