There are a plethora of varied skills required to be a leader. It takes a true willingness to learn in order to begin to acquire a tool belt of skills.
One of the things required to be a leader is discipline. A leader needs to be an example to the staff of someone to aspire to be like. This is why many people in America get disappointed when their president fails to uphold these standards. It is disheartening when a leader is not a tad better than the lowest common denominator.
Another way to look at the skills required to be a leader is to realize that leaders are fallible. The best ones will publicly and privately admit their mistakes and aspire to be better. The worst type of leaders are self righteous individuals who spend all their time covering up their mistakes. It makes one wonder if that leader has the habit of lying to get ahead.
