For you to blame your bad attitudes on another person or on a difficult circumstance is simply a cop-out. If you allow events and people to cause you to be negative, you are only hurting yourselves more. In addition to everything else you are now forced to live with the effects and misery your bad attitudes will bring.
Take time out with yourself! The reality is that YOU help create the atmosphere in which you live by the words you speak. When your words are positive, you produce a creative, loving, accepting, positive environment.
