Everyone is a leader but the best leaders have developed a solid enough understanding of self to not let their ego or triggers influence their work.  Great leadership is usually about doing far less than more.  Its counterintuitive but it works.  Being a great leader takes constant development.  We are all born with the capacity to lead.  As we grow up, that capacity is either grown or reduced through our conditioning and experiences.  Its true that some personality types naturally like to lead more than others but it isn’t true that your leadership capacity is just a function of nature.  I work with leaders to identify and do more of what works for them and their teams and less of what doesn’t.
