You have tried to clean out closets and clear what some people call clutter, but you keep hitting that sentimental roadblock. Even though you may not be using the childhood books or the set of blue vases anymore, you just don’t have the heart to send them away to an unknown place. How about a reverse housewarming party? Invite your friends over and ask each person to pick some items to take home with them. This is a great way to reunite with old friends and declutter at once.
