"Declutter" is very simplistic without explaining to op HOW to declutter
My top tips for decluttering:
If you haven't used it in a year (covers seasonal variations)
If it's not of sentimental value
If it's not genuinely potentially useful (eg tools, fuses & similar)
Get rid!
Totally agree with everything needs a home!
But PLACE those homes where they make the most sense -
I have my recycling bin right next to the door so any post I'm binning goes straight in there!
I started when I was first married and no longer living in a studio/bedsit (I married young) with the laundry hamper being down in the kitchen near the washer as I thought that made sense, but actually it was much easier having it in the bedroom where we undressed as otherwise we couldn't be arsed at the end of the day trailing down to the kitchen and so often ended up leaving dirty clothes in a corner, forgetting to take it down of a morning. Even more so once we had dd it was easier to have a hamper near the changing "station" (not a proper station, just an area we set up)
Note where you INSTINCTIVELY go to collect/put away a thing if it's not CURRENTLY where that thing lives and change it's home. Agree also this applies to items regularly lost! Change the "home" to the first place you're looking when you need it.
I'm cursed with a TINY kitchen yet I am usually a keen cook and baker - it's like playing sodding krypton factor at times!
But...everything has a "home" so I know where it is, I even inventoried my food using the nest egg app at start of lockdown as grocery deliveries were being a bit hit and miss and on it you can create your own "locations" and I've done so such that I know exactly what shelf and in what cupboard things are.
Also agree with not leaving a room empty handed. I'm disabled now so moving is difficult and painful so I'm not as good as many pps for tidying up immediately after say a meal but the next time I'm going to the kitchen anyway I'll take the dishes through etc in my case to minimise how often I need to move!
Set aside one day a month for the "stomach sinking" jobs - but don't do the same one each month! Eg one month it's the kitchen, another it's the hall cupboard, another it's one persons "wardrobe" (I made sure I did this seasonally with dds clothes and charity shopped the ones she'd outgrown)... you get the idea
I have upbeat music on when I've longer jobs to do, really helps
