There’s no universal answer to it, as it all has to do with what habit can you install for yourself that will ensure that you are reminded of the “pending” things to get done “sometime this week/month” One approach would be to put the checklist on your Weekly Review, and when you notice that something needed to be done, clarify the next action, and park that on the appropriate action list, with a due date by it (e.g., confirmation calls and your student’s lesson plan), and perhaps another notation on the calendar for the day it had better be completed by.

You have as many next actions as you have, and, yes, you should be looking at everything on your Next Actions lists (by context) when you have any discretionary time, and you are in that context. So, yes, they should be reviewed sometimes several times a day. You need to relate to your Next Actions lists as your “real to-do lists” as much as your calendar, and save the calendar for “they-die-if-not-done-that-day” things. It’s good to put the due dates on the actions on the lists as well, as an extra precaution.
