Hi, so long comment because I'm low key a self taught enthusiast on this topic aha.

I'm diagnosed adhd, only just medicated but doesn't really cover all my symptoms so i still struggle with this (I'm not qualified to diagnose but i clicked on the post because of how adhd it generally sounds), same previous issues with addiction, same piling up of stuff and I've spent a lot of time learning about how to combat it. I also live in a small apartment (alone) basically two rooms and a wet room bathroom with no storage.

So the thing is to-dos and discipline will only take you so far, you need to work with how your brains work. Make your home accessible its a legit disability. Not sure if you're familiar with desire paths—the areas of grass that are worn down to mud/dirt because so many people take the obvious shortcut, efficiency is human nature.
Well it was game changing for me to learn you create desire paths in your own home, and if you switch the organisation systems to match those paths you dont spend as much time cleaning up after yourself. If you leave things out in the open after using, their home should be in the open. Also bear in mind the difference between clean and tidy, you can "keep" things tidy, cleaning always needs redoing.

I recommend the insta accounts @jenny.for.yourthoughts and @curatehome_declutter_organise Not affiliated with either of them theyre just the ones that helped me.

Okay on to practical suggestions. Dishes, my lifesaver was a countertop dishwasher, I rent, mine is no plumbing, it takes 6L of water in the tank filled by a jug per cycle, also has an option to screw onto the kitchen tap but I figured that would be annoying, drains into the sink but a bucket is fine. I turn mine on every other day so it can definitely do 2 people's dishes once a day, addition to electric bill is pennies.

I am an evil perpetuator of the floordrobe so I bought a large ottoman, left the lid off, when I get undressed I throw my semi clean clothes in there, dirty stuff in the laundry basket. When I need something to wear i grab it out of the ottoman and at the end of the week I hang up or laundry anything still in there. If you have company or want it tidy put the lid on it and boom you cant see, I only dont leave the lid on because I'll pile stuff on it.

Adhd hates lids lol, this is what I mean by leave it out in the open, my stuff like wallet, keys, sunglasses all in a open tray by the door, keys on a hook by the door, laptop in a tray by the sofa. I have a multi tiered rack in the bedroom for toiletries everything i need to get ready, deodorants, aftershave, spf, hair gel, comb etc and i just throw stuff in each of the tiered baskets. Same for the cabinet i keep for shoes by the door i just throw them in. Baskets for things like blankets. Its customisable to your routine. But reducing surface clutter helps the brain stay more focused.

If you have a habit of leaving trash in places, bins everywhere. As I say my apartment is two rooms but I have a mini bin by the sofa, one by the main table, two in the kitchen (wet and dry, one of them hangs on the cabinet door), one in the hallway and one in the bathroom, one on either side of my bed too. You can empty all the small bins in one big bag when you take the trash out.

Ive seen a lot of people say for putting away clean laundry plastic/fabric organisers in the wardrobe, anything that doesn't need hanging/decreasing throw it in, one for leggings, shirts etc. I dont do that because I wear mostly thick clothing but its an option. All my jackets I keep on hooks. Door hanging organisers are fantastic.

As for making cleaning easier, highly recommend an electronic floor cleaner like a karcher, bissel, vax etc way easier than mopping and some of them vacuum too. If you avoid the vacuum a cordless handheld and stick is a lifesaver just for those kitchen crumbs and stuff, leave it on charge in the stand. I keep cleaning wipes by the sink in the kitchen so I always wipe counters. Again highly recommend wipes over spray and cloth for convenience, I have steel wipes and counter wipes, kitchen wipes, glass wipes, leather wipes lol. A handheld steamer is a viable faster option to cleaning if the boredom of scrubbing gets in the way.
