What makes a leader?

This idea of what is a great leader has been fumbling around in my mind for a long time.  What makes a great leader?

Is it charisma?  is it status? power? Money? social influence?

I am still not too sure, but the one thing that I think every great leader must have is a vision... a vision based on a value system that contributes to making the world a better place.

A great leader has a vision of what their world, their country, their region, or what their community could/ should look like and a leader wants to get to that place.

Personally, I want to see a world where the stigma surrounding mental health is eliminated.  Where fluctuations in mental health are seen as normal functions of daily life and not pathologized as an illness or moralized as weak or not normal.

I want to see my community support people with mental illness by facilitating them to be able to live and contribute to their communities.

I hope to be able to contribute this this goal.  But what is it going to take?  How do I get there?  Will you help me?
