A person's ability to expand their circle of influence. 


To be a good leader one needs to be competent in their area of expertise and demonstrate good character.  To gain respect from subordinates and peers one must lead by example.  Leaders pass on competency skills to others.  They love to mentor and help others become successful.  They teach the importance of strong character and reinforce it with their own behavior.  They provide solutions to problems rather than just identify them.
