CH (the host) is examining the power of service.  She encourages listeners to utilize their strengths and talents to help others.  These gestures do not need to be grand.  Service offers benefits to both givers and receivers of the kind acts.  The benefits include obtaining support, encouragement, motivation, and inspiration.  Both parties can use these experiences to overcome obstacles in the future.  Service unites us as human beings.  When we work together, we excel.
