Seriously cannot underestimate the benefits of doing full length PTs at least once a week. Learn how to block out all unnecessary background info intuitively. I personally don't find diagramming to work for me, but I gave it a shot for a month and can conclusively say it doesn't work for me- so 100% try it (I know it saves some people) but also be totally fine with not needing to use it if it's not for you- don't force it is basically what I'm trying to say. Stay on a schedule where you give yourself 1 to 2 days off a week (I work FT so this is extra necessary for me) in order to not feel burned out.
