Enthusiasm releases the drive to carry you over obstacles and adds significance to all that you do. It tones up your physical vitality and gives warmth to all your personal relationships. When you associate with enthusiasm long enough it grabs you and takes over within you.
Norman Vincent PealeThe word resentment means to re-feel...to feel again. Someone wrongs or wounds you; in resenting it, you re-feel the injury. And you re-hurt yourself. The Hebrew Talmud says that a person who bears a grudge is "Like one who, having cut one hand while handling a knife, avenges himself by stabbing the other hand."
