Getting the first miles in
I finished the draft of the third chapter today. After some proof reading of my own, it will be off to the editor for the first review. After writing a couple of chapters, it's a good time to do a bit of reflecting on the go.
I really enjoy writing this sort of content. Having the structure of the entire book laid out beforehand also really helps in making sure that I focus on a specific topic at a time. Without, I think I would be tempted to start drifting off topic by elaborating on more niche or advanced techniques.
