I'm loads better than I was. (Also have MH issues and fatigue.)
I use three Flylady techniques which I learned years ago and they work so well.
Five minute Room Rescue. Set a timer for five minutes and see how much you can improve how a room looks in that time. Chuck out junk mail and newspapers, empty overflowing bins, hang up coats and bags, stick dirty dishes in the sink, plump up cushions, wipe dusty surfaces with a damp cloth. All this can be done in five minutes. It is amazing how much better the place looks. And it inspires you to do it again as it is so easy.
I use 5 minute timers to kickstart the day: unload dishwasher and reload with stuff from DC's midnight feasts
Wipe down kitchen surfaces and stick a washload and the kettle on. Makes me feel like I've done something first thing.
The next one is '15 minutes to company ready'. That means you set a timer for 15 minutes and use it to get one room of the house looking good enough for unexpected guests. So if it's the living room you start wiht the 5 minute room rescue stuff then hoover the main sections of the carpet and polish surfaces.
If it's the kitchen, do the dishes, clear and wipe the table and surfaces, mop the floor.
The final one is the One-hour house blessing when you spend an hour doing a quick surface clean of the house broken into 10 minute chunks.
Declutter (get kids to put away sports kit, bags, toys etc while you do yours)
Change bedding (get kids to strip beds while you make them. Or get them to do pillows while you do sheets and duvet covers.
Hoover (I put a bit of cottonwool soaked in essential oil into the hoover each time to make the air smell good)
Dust and polish (DC dust with feather dusters and I polish)
Wipe down bath, basin, loo and change towels
Empty all bins
Flylady has loads of easy tricks to simplify things.
Use a no-rinse diluted floor cleaner in a spray and a swiffle mop that sweeps at the same time to do hard floors. No buckets of dirty water to deal with and the floors dry almost instantly but they really are clean.
Clean baths and basins with shower gel or bubble bath! No need for special cleaning products So obvious really. No harsh chemical residues or sour smells. I barely ever need to scrub the bath now. I just wipe it down with the existing bubbles as the bath drains and then rinse it with the shower head. It always looks really clean.
