What a simply super idea.
So, once a year, you look around at the pigsty that your house has become.
You take action.
Biggest pile, out the door.
Next biggest pile, out the door too.
Keep going, keep going.
Then when you get to the pile with the Stradivarius and the old stamps, have a break.
Then come back next year, and do it again.
Don't do too much inbetween, and especially, don't buy anything.
The stuff that goes out the door, make sure that the charity of your choice gets first go at it.
"Hello, is this [charity of my choice]?"
"I put some stuff out the front of my house, including the violin that didn't get made by Stradivarius, but by his brother Nokov. Could you come and take it away by Monday please, except for what you don't want?"
Then you sells the rest on eBay, or the council comes by and removes what you couldn't.
You need never clean again, until next time, or until the Lord returns.
