Today, around 3 AM, I finally submitted the last chapter in the book.
I was surprised to realize that it took over a year to write it, and I am happy beyond words that the action of writing the book is behind me.
That said, it is not actually the end of the work. All it means is that I am done writing new content, now we are going to get into a cycle of editing once more, and I really don't look forward to re-reading what I wrote five to ten times, over and over and over again.
Nevertheless, I am feeling GREAT!
