Housecleaning and Mind-Easing

I tell you something that is really weird. Whenever I clean my house, my mood improves. I cannot really understand why, but I think there is a definite effect. When my office,house, and car are a mess I feel like a mess. But when I clean all of them I feel better about the challenges that come to my life as well.

Is that normal and borderline psychotic, or is that true of the rest of you?
