de-junking

I've heard more than once that letting go of physical possessions, the "junk" in our homes, can actually free you mentally. I've been doing some major de-junking of my sewing stuff, and in other rooms in my house, and I have to say, I really can feel the difference. It's weird. But good.

Real question is, how much will this impact my personal/mental self? I mean, I want results from this, more than just the organized and less-crowded space in the house. (Ever notice how you want to dance in freshly cleaned spaces? or is that just me?)

Not that the clean house isn't enough. I'm just hoping for something more transcendent, as a bonus.
