i think it's easier to clean from total chaos which is why i say it get worse before it gets better. when you're trying to tidy an untidy pile of stuff, you're picking things out slow, one at a time.
Dump it on the floor and clear the space you're trying to tidy, then as you go thru the debris, bin what you don't need and put back what you do.
the dvd's were a nightmare.. 300 odd, most of which weren't in boxes.. so, boxes go ina pile on the floor, spread em out, then it's much easier to see the right box when you pic a dvd out the other pile.
or alternatively, end your life of materialistic obsession and burn it all. I would say give it away, but i'd still have to tidy it all if i did that.
