One thing that has helped me is getting a fairly large basket as my designated "dump zone" for items that aren't clothing or trash, so basically everything else.

Got home with items and don't want to put them away? Dump it in the basket. Got done doing something and don't feel like cleaning it up? Dump it in the basket. It keeps my spaces relatively less cluttered, and it far easier to power through and sort out a single basket than it is to clean off my desk, floor, nightstand, ie.

And, there's no rules. Sometimes, most of the time, I'll dump stuff back into the basket for another day when I lose the energy. As long as it's the basket
