Be ruthless. We moved house (a-bloody-gain) last year and it took ages to sort through stuff, what to pack what to chuck.
Things build up slowly, but I refuse to live amongst what essentially is junk! My friends think my house is an oasis of effortless calm but I'm a hoader and it kills me to throw stuff away - but I LOVE my house when it's tidy.
Once you've tidied a room and can stand back and 'breathe', it's a wonderful feeling that you'll eant to replicate everywhere else.
If DH is being a bitvuseless (as I can be, I know), keep one box for his stuff. If he doesn't help with tidying or organising, just chuck his stuff in his box. My DSis did this with her DP (now DH), she allocated him a basket - Ithought she was treating him like a dog... until I had a DH of my own!
I don't go to bed unless the washing up is done, no matter how bloody tired I am, how much my back.hurts.
Laundry is hung out in order, ie DS stuff together, DH stuff, my stuff, so when it comes off the line it is all batched up in groups, then it is upstairs and dumped into relevant drawers easily.
If I iron, it is just one thing Iwant to wear that day. DH irons his own badly and I don't bother with DS's. So no piles of ironing.
When the kettle is boiling, I'll tidy counter top, or wipe up crumbs, or put dry dishes away, or whizz round the sink with cilit bang, or go through some receipts, or check cupboards and frudge and add things to a shopping list. I get a lot done this way as we drink a lot of tea!
We have a cupboard near the front door that is a bit of adumping ground for: keys, receipts, minney-off coupons, spare change, sockets protectors, loyalty cars, safety pins... I have a pretty wicker basket that holds it all in one place and go through it weekly.
I keep my make up on a shoebox lid in my top drawer in my bedroom: open drawer, get out lid, apply make up, put lid back in drawer. Ta-da! Can't see bottles and brushes and crap lying around everywhere.
Every little helps. As soon as you start you'll feel better for it
