Good leadership in the modern age more importantly requires attitudes and behaviors which characterise and relate to humanity.
Good leadership involves serving the organization or group and the people within it. Ineffective leaders tend to invert this principle and consider merely that the leader must be served by the people.
Of course leadership involves decisions and actions relating to all sorts of other things, but leadership is special compared to any other role because of its unique responsibilty for people.
Good leaders are followed chiefly because people trust and respect them, rather than the skills they possess. Leadership is about behaviour first, skills second.
This is a simple way to see how leadership is different to management:
Management is mostly about processes.
Leadership is mostly about behavior.
