Too Much Stuff!

This morning I went down to get the mail. I returned at about 12:00pm. We've had lunch and I'm reviewing the situation, so to speak. I'd like to do something about some of the stuff I have. What can I do without? What can I get rid of? Every so often I have the urge to get rid of stuff. This place is too small and I feel like I have too much stuff. The thing is that all the stuff is useful and I will use it from time to time. I need another person's input into the "stuff" situation. Maybe it could just be rearranged. Help!
