If there is open space in my closet, desk or drawer, I should fill it up with something.
Some people cannot stand having any surface open. If it is empty, they want to immediately fill it up.
It is a great exercise to have at least one area in your home that has absolutely nothing in or on it. Not only is it good feng shui which creates a vacuum for good things to enter, it helps you realize that most possessions require a lot of time cleaning and maintaining. Dusting off an empty shelf takes about two seconds. Dusting a shelf full of trophies can take over 10 minutes! What is more valuable – your time or your possessions? This is absolutely your choice and whether you realize it or not, you do choose every time you bring something new into your home.
