My house is always clean, tidy and with no clutter.
As other pp have said, there are several reasons: I can't stand clutter, it makes me edgy. Clean and tidy makes me calm, happy and free to do other things. Actual cleaning is so much easier when there's no mess to move first.
Secondly, I continuously declutter and don't keep random stuff I don't use. Lots of things are given away/go to charity. New clothes only if needed and then old ones straight in the charity bin.
Thirdly, I tend to keep quietly busy all the time, doing things. I say "quietly busy" because I'm never dashing about, never frantic, I just "potter". But I don't understand how people sit and do nothing! How do you do it?
I mean, if I'm watching my favourite TV show, I'm probably doing the ironing and folding up/putting away at the same time. If I'm in the kitchen making a cuppa, I'm probably putting the clean dishes back in the cupboards while the kettle boils. Folk sort of stand/sit around doing nothing....isn't that a bit dull and boring??
Fourthly, every single thing has a place, and it goes back in that place when I've used it. Scissors and selotape? Back in the stationary drawer. Clothes been through the dryer? Back into the wardrobe and sock drawer. Arrived home with the shopping? Keys go on the key rack, coat on the peg, shopping in the fridge/cupboards, shopping bags folded and into their store box, handbag and purse in the bedroom where they live. I don't just DUMP stuff as I move about....
