Where in your life is it easy for you to make a commitment?  Where is it harder for you to stay committed?  Dig deep and see what patterns are there.  Is there a certain area of your life that it happens in?  Ask yourself, what is it that keeps you from following through with your commitment?  Are you sabotaging your efforts?  What is that about? What would it take to make a shift so that you would be able to follow through with your commitments in all areas of your life?
