Simply yet effectively stated, to exercise the priesthood is to serve others. Therefore, the happiness of a priesthood holder is eternally linked to service. In fact, Marion G. Romney says

Both the act of service and the heart-felt desire to render that service ultimately ties into the very soul of a priesthood holder. While we may be effective at rendering service when asked, the distillation process (of the doctrine of the priesthood as the dews of the heaven) transforms the priesthood holder from one who simply responds to requests to serve, into one who actively seeks to serve from his heart by his own free will. Seeking to serve Heavenly Father's children will involve an active, continuous observation of people and circumstances as well as perpetually seeking guidance from the spirit for promptings as to when and how service may be rendered.

While the world takes typical leaders and places them at the top of an organizational chart with those below who are meant to serve those leaders to some specific degree, the priesthood upends that chart and places priesthood leaders on the bottom and makes them a humble servant of all. The Savior taught this to the apostles following the last supper.

Finally, the priesthood holder learns and comes to understand that their call is to minister to souls and focus on the condition of a soul rather than efficiencies of programs intended to increase effective ministering. While programs to minister do exist in the church, they are merely a means to an end, which is to establish personal, one-on-one ministering. When the Savior washed the feet of the disciples, He did not stand back and instruct them on how to do it simultaneously so that it could be done more quickly and efficiently. Rather, He washed their feet one by one, giving service to each personally. Such is the ultimate demeanor of a priesthood holder as well as sisters who access priesthood power through their covenants.
