While most public decisions are made by committees of people, individual leadership is important to the final outcome. Different people have different skills and each one is valuable in the decision-making process. The top leader in a group, however, is the person who can synthesize those various ideas into a cohesive package that leads to a final decision. Personality does matter. People who get along well with others are generally more effective leaders.
Wide views are more important than narrow perspectives.
Those who can keep some distance between themselves and individual issues are generally more effective than those who pursue single agendas. People with narrow agendas in public life usually wind up sounding like a broken record. Those who have the ability to weigh the issues and keep the various issues in perspective usually wind up making the best decisions. A focus on public service rather than self-service is important. Those who enter public positions thinking they will find a way to enrich themselves personally generally make bad decisions.
