In reading a blog on the net , I came across the idea of the 50% Space to Stuff Ratio This was new to me but may be old stuff to some of you.  

The concept is that you are to evaluate the floor space in your home.  If it is almost completely covered, there is no room left for new opportunities to come in.  Reduce what is on it by 50% and there will be room for movement and the ability to change out what you want for now and for the future.  When you have an open house and there are a lot of people in the room - they need to be able to get around.

Then when you bring in something new, something old goes away - far away- permanently.

This will help considerably with your organizing, as there will be less to organize. Once your home is ready to be sold, you will not have all your stuff to deal with.  What is left is what you really want to keep and/or need.

This may help in explaining things to clients about how much to remove before staging.

Once again, it is 50% available space to how much stuff is in that space, for some you may need to give a 75% figure.  Men probably like this numbers concept better than most women, we go more by how it looks.
