Have you ever met Debbie Downer, Negative Nancy or Pessimistic Patty?  These people can be so entrenched in the bad things that there isn’t any room for good things to grow.  They inhabit our families and social circles.  It can be emotionally draining just being around them, and you must be careful because their attitudes are contagious.  Negativity perpetuates itself, breeds dissatisfaction and clutters the mind.  And when the mind is cluttered with negativity, happiness is much harder to come by.
