Had to backtrack a bit. Chapter four had some tougher concepts that required a reread. I’ll probably have to read it again. Too many challenging concepts for me to do this in audio so I had to switch to the kindle

Switching to printed book on this one. And probably need to reread chapter 4. We’re stepping into some challenging to understand territory.
