People who own junk always have a great many handy boxes. We think that they will become organized if we introduce the correct system.
Not so! Once the junk is filed away it makes room for more junk- often duplicate junk. All we have done is made little junk houses where junk can hide.
Sometimes we need to make things worse before we make them better. Throw away your storage units! Tip your junk over the floor and make a decision on each item. Make the junk so dreadful that you have to deal with it!
