I am continuing to go through items to get organized and simplify. I resorted back to some guidelines I made for myself a couple years ago. Hope they help you.
1. Throw it out if it's...
...broken and unfixable, or unlikely that it'll be fixed in your possession
2. Give it away if it's...
...been usued/untouched for whatever amount of time makes sense to you (1-12+ months)
3. Keep it and give it a "home" if it's...
...keeping with the goals/theme of the room.
...neat/organized in appearance.
...used frequently and in good shape.
...going to be bought again if it were given away.
What are some guidelines that help you reduce your "stuff?"
