Your list looks reasonably complete. Personally, I've automated most of the tasks above in my calendar. Otherwise, I've added them into whatever task tracking tool we use for projects, which in my case would be template cards in Trello. In the rare occassions that I'm idle at work, I just continue reading whatever nonfiction I have in my queue on my shelf. Currently, I'm reading The First 90 Days. Might be something you'd find useful as well.
