As the world pays tribute today in South Africa for Nelson Mandela, it requires a moment of reflection on just what kind of man he was. The sacrifices he made. And the changes he single-handedly brought about. Not only a change in a country, but changes that have been spread worldwide. 27 years in a hard labor camp and he never waivered from the cause he was chasing.  And then to become President of the country that he had already transformed. To compare him to the great leaders of all time is truly an understatement. RIP Mr. Mandela.
