No good news here - all I can offer is to be living with one

I shared a house with a neat-freak and she trained me really well. It helped that her eye would twitch if I left any mess around. She was constantly moving and it's hard to sit on your bum with someone like that in the house.

Same with exH, he was amazing so lots of it rubbed off (not THAT much though). Now I'm on my own I've gone straight back to my crap ways.

HOWEVER, I will say if you can go MENTAL and do everything one day - it is so much easier to maintain it.

I also have little competitions with myself ie - if I boil the kettle I do as much in the kitchen as I can till it boils and the tea steeps.
When kids in the bath, I tidy the bathroom.

I fold the washing in front of the telly , and race to put it away in the ads.

ETA - and Angel Punks does 'the waitress' thing, which I highly advise. She doesn't walk anywhere in the house without picking something up along the way.

And if all else fails invite someone over for lunch so you a FORCED to tidy.
