I also completed most of a new chapter of the book, but it's not done yet.
Two-fifths into the work week and I've taken care of three-fifths of my to-do list. Not counting the stuff that will get added.
I always feel like when I have big things to do that require big chunks of time, like this new script, I first have to clear the decks of all the little stuff. So the next couple of days should be really productive.
