Before you fall in love with the latest gadget, ask yourself: "Where will it go?"
Eliminating clutter isn't easy, especially if you keep acquiring new stuff to replace the stuff you get rid of, so you need to spend just as much effort on making sure you don't add to your mess as you do cleaning it up.
It's like taking one step forward, and two steps back. Your objective is to have LESS stuff, not more, so it's essential to resist the urge to bring in new items unless it's absolutely necessary. In fact, even if you find something new that is actually useful, you still need to ask yourself "Where will it go?", because even a useful item will only add to your clutter if you don't have a place for it.
