I also like the idea in principle but find it hard in practice. Some of this has to do with the fact that I enjoy lots of activities and each comes with a certain amount of gear (though there is some overlap) so that is one way I end up having what feels like too much stuff. I am also the kind of person who likes to be prepared for a variety of situations, and this can also lead to accumulating stuff that gets used only rarely--it's always a battle between the desire to be prepared for things that come up vs. the desire to keep the amount of stuff under control. Usually every year or two I get sick of clutter and get rid of some things I haven't used in a long time, but it would be nice to not get to that point in the first place!
