"Out with the old, in with the new"...
While I would love for that to be the case it's not always possible or affordable. I would love to redecorate my home with the New Year, but since that's not happening how about a refresh!
By thoroughly cleaning it gives me a chance to go through my things and see what changes I can make. I may move the furniture around, change out some family photos, even move items from room to room!
