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 did this too, but it backfired horribly. I got like four packs of identical socks. But I guess two came from a different batch, because they feel different. So now I have to spend twice as much time pairing socks by feel, rather than simply being able to grab and go like I originally intended.
Oh. No. That sounds horrible.
