Fear

If Hope lifts us, Fear cripples us.  When you fear, you worry about something that has not happened yet.  If it hasn't happened, why spend time fearing it? Many people spend countless hours imagining what MIGHT happen, and then worrying needlessly, as well as becoming crippled by their thoughts.  They never realize their true potential in life, they set limits for themselves so as to avoid fearful situations.  They've capped their own existence.  Train yourself to deal with the circumstances in front of you, focusing on the here and now.  Carpe Diem!
