I have done a lot of work but I have a lot of work left to do as well.
Right now, I'm rewriting/revising/editing through the first 40-50 pages of my presentation notes which are about 160-170 pages in length as of right now. About 75% of that is a fresh rewrite, although I'm going to have to revise and edit that too eventually.
I also have a head start on the book. So far it's mostly backstory and personal context which is necessary to understand how I got to this point. I need to streamline chapter 5 as it contains a lot of redundancy. I probably ought to revise and edit the first 4 chapters too.
I'm getting close to the point where I'm running out of major topics to cover but I have at least one or two more that, for sure, warrant coverage before I call it a finished work ready to be submitted to a publishing house for review.
That said, my hope is to have this published before the end of 2026. As a first time author, however, I have no idea how long I should expect the publishing process to take. I'm kind of thinking that I could have my manuscript finished by early spring which leaves half a year for professional editing, printing, etc. to happen.
