I've developed better strategies with time and resources like Marie Kondo, The Organised Mum and A Slob Comes Clean (Dana K White). It's not instinctive to me and I was raised by a hoarder so entered adulthood with pretty much no tidying skills and tidying/ cleaning up was a monumental mental and physical effort which developed an overwhelming cycle.
I suspect there is ADHD through my family. My DCs are ND.
Interestingly, a lot of SM organisers are ND (Clutterbug and Dana K White come to mind) and they've had to manually develop systems.
Strategies that work for me:
Mirroring (having someone doing something in parallel at the same time) I subscribe to TOM Rocks "guided cleans" with instructions (they range from 5 mins to 2 hour house resets). I also like videos if it's something static like folding laundry.
Keep things near point of use. The easier it is to put away, the easier to maintain. Keys are hooked near the front door- I have to go past it. In the kitchen the spices are next to the hob, the cutlery next to the dishwasher.
What type of organisation suits you. Clutterbug is good for this. I am not a minimalist, and I need the visual prompts of seeing things. My DCs have mesh drawers in the wardrobe so they can see what's in the drawers. I don't want a minimalist house with lots of bare surfaces- I find it unsettling and I wouldn't have those visual prompts.
Break jobs down into small chunks of time. Spend 10 mins dealing with a drawer/ corner and tick it off. It's not so intimidating. You might gain momentum to do the other zones. Don't aim to blitz a whole room in an epic, overwhelming mission. It's easier to clear things out in small installments too. Making things X minutes better is more acheivable than setting a big pass/ fail goal like "tidy the lounge".
Work out where to dispose of unwanted items. Don't complicate it. For clothes, I'll never manage to sell on Vinted. The best bits can go direct to the charity shop. Bulk stuff to charity banks. The best way to manage stuff is to avoid buying excess in in the first place. That's where the financial cost is made and that's where the environmental cost is. Don't get hung up on hypothetical value- it is only worth what someone will pay for it in the immediate future.
Work out what is blocking you. My kitchen normally backs up because the bins need emptying. If I shift that first and get the dishwasher going, everything else can start flowing.
It doesn't have to be perfect all of the time. The house is a mess right now after two weeks of family at home. But I have a strategy. My dishwasher has just finished its second load of the day, so I can crack the kitchen tomorrow. The laundry is being blitzed so the DCs have uniform tomorrow. Tomorrow, I'll use a multi-room reset to spruce up the living spaces. It's doable in an hour so I'm not phased about it or driven to a rage clean where I'll burn out getting everything immaculate before letting it look a mess again a week later in a cycle of despair.
