Clutter is not differentiating between what is needed and not needed, wanted and unwanted, necessary and unnecessary.
Clutter is choosing not to decide.
Clutter becomes an unwanted guest, a hobo claiming squatter's rights in your mind and in your home.
Clutter takes up the space where abundance and prosperity should be.
When there's no clear space to sit down and write a letter, it's time to clean the proverbial house.
