5. Less is more.
Material possessions won't make you happy, sweetheart. They do not contain memories. They do not measure your worth. So clean your closet out every season and donate what you don't wear. Keep memories fresh in your mind by talking with others, telling stories, writing and remembering, and only hold on to a few special physical keepsakes. Keep your home and work space free of clutter (organized chaos is okay!) and it will help keep your mind and spirit free of clutter, too!
