Summary of Leadership Qualities

I have been asked what the four important aspects of leadership were in the post that I wrote.  Actually, when I went back to read it, I spotted two more.  They are:

1. Concern with the individual in a team/organization;
2. Objective driven;
3. Teaching the objectives by instruction and example;
4. Making individuals and leaders accountable;
5. Unperturbed by the popularity of his stance; and
6. Proactivity.

Have you had a leader that you admired or made an impact on your life or view of life? What leadership characteristics were used?
