Sufficiency........................

68.  Nothing is sufficient for the person who finds 
       sufficiency too little.

71.  We must put the following question to each of 
       our desires: What will happen to me if the 
       object of my desire is achieved?   What will 
       happen if it is not?

77.   The most important consequence of self-
        sufficiency is freedom.
