There are many articles on the Eisenhower Matrix, but here’s a handy infographic from Asana:

I’m trying out Todoist’s rather fixed priority setting thus:

Priority 1 = Important and Urgent (or what I call “Do it”)

Priority 2 = Important but Not Urgent (or what I call “Plan it”

Priority 3 = Not Important but Urgent

Priority 4 = I should probably either prioritize or junk these tasks

GTD has you avoid prioritizing tasks, but I never found a large body of tasks, even properly organized into projects and contexts, deferred or active, to be useful for getting through a day. I can’t say for sure that this scheme will work, but I do find myself working off of Todoist’s Today filter and then my “Do It” and “Plan It” filters each day.

Do It filter syntax:

    @important & @urgent | @Today | Today | p1

Plan It filter syntax:

    @important & !@urgent | P2
