My recommendation is a small thing: a trashcan with a swinging lid!
Covers the trash, reduces smells, will prevent trash tetris (sometimes), and very good instead of foot-pedal opening trash cans or trash cans put in a cupboard.
Another thing are toothbrush holders that stick to mirrors. Might jog that memory of needing to brush your teeth!
Wall-mounted keyholder by your door, too. Anything I put on a flat surface will eventually be lost or covered with more junk & papers. My keys are WALL-ONLY!!!
What item(s) have helped you with your struggles?
I have a bum bag (Fanny pack, hip bag, waist bag) which had my wallet, headphones, emergency spoon, and keys. When I get in it is put in the landing strip, when I leave it goes on. I have not spent 20 minutes panic searching through pants pockets on the floor since getting it.
Go on…
Yogurt happens
Oh, well that’s better than heroin.
