I’ve done this. I also do things like move my keys to my left pocket, when I need to remember to take something home from work, normally, my keys are in my right pocket. When I run out of something in the morning that I want to remember to get after work, I’ll just take the empty box out with me and toss it on the passenger seat, rather than opening the notes app and adding it to the list. I might not remember that I want to get something after work, but I will see the empty sandwich bag box on the seat, for instance. I have a slow leak in one of my car tires, it only needs filling about once a month or so. When I need to remember to fill it the next time I go out, I’ll put something on the hood of my car, so I see it and remember before I leave.
