Step 2 is go through each and every closet and drawer and purge the items the same way you did in the rooms in your home. (remember to do this successfully, you must get tuff with yourself.) It is a good idea when going through a child's or spouses items that you allow them to be a part of this process. This way you don't let go of something that is very special to someone.
I will share a few of my organizing systems that we use in our little home.
