You go to your local big box store and buy volumes of toothpaste, dental floss, pantry foods, tissue paper, greeting cards… only to come home and find you already had volumes of these items scattered about.  SAVE MONEY!  GET ORGANIZED!  Categorize your things based on how you use them, and which room should have them.  Doing it now prevents you from wasting time searching all over the place for something later and keeps track of household items running low.
