There are two main principles on how to achieve sound leadership:
(1) Every decision and action must be in the best interests of the people involved
(2) Every decision and action applies consistently to everyone, including and especially the leader
Benevolence cannot be achieved if the leader is self-centered. Discipline cannot be achieved if the leader cannot control him or herself. Focus on helping others and improving yourself constantly. Don't think that helping others is enough. A spoon can be very useful but no one follows a spoon. But serve as an example to what constitutes a proper man or woman also and others will try to emulate.
