As you know, I set a deadline to finish my book: 8/15. It came and went yesterday. Still not finished. I figured out some things about 3/4 of the way through that I had to go back and fix before I could move forward and finish.
That's the best part about goals -- you can reach some and not others, but you can always make new ones.
By the end of next week, THE END will be on my page.
