I think the way to get a handle on all your stuff is to turn your life inside out (or more accurately, turn it rightside out). From an engineering standpoint, you have to design your life. You know - architect how you want to live. From that, it's easy to deal with your stuff -- does it support your design? If it doesn't, it should go. The computer should have a place. Kitchen stuff should live in the kitchen. The bedroom closet is for the clothes you do use and maybe seasonal stuff at the top. It isn't for 6 boxes of cat5 and all those extra USB cables you end up with. You should not have a closet or garage full of "misc". My personal test is the "might" test. Stuff you "might" need is not stuff you do need. It goes.
