Two years. I started writing it in the fall of 2015. Again, since it was for clients, my assumption as I wrote it was that I would personally know more than 90% of the people reading it. I think that because of this, the book has a very personal tone to it – like it’s a letter from a friend. However, as I wrote and researched, the project grew into what you see today. The main writing part took about six months. The rest of the time has been editing, refining, and graphic design.
