I have a list of completed TODOs dating back to July 20, 2020. I keep a running, open TODO list in the Notes app on my Mac, check things off throughout the day as I finish them, and close out the day's completed items that night or the next morning. (or sometimes a few days later when life dictates that I have other priorities.) Sometimes the completed todo lists are as simple and profound as recording the birth of my son. Other times, they capture a dozen or more mundane tasks that I needed to track and complete in a single day. Either way, I find satisfaction in manually clearing out the previous day's completed TODO items, and have found that keeping track of daily tasks in this way makes it incredibly easy (if a bit time-consuming) to write year-end self-evaluations of my job performance. I regularly forget about several major projects that I was involved in, and only remember by dint of my TODO lists. I should add that I use the Notes app because it's installed on—and syncs across—every computing device I use, and because my wife is happy to use it too, so we can share some TODO lists, like groceries or house chores.
