The measure of politicians is not their words but what they do to improve the lives of their people. A successful lawyer, Nelson Mandela sacrificed career, family and freedom to pursue an extravagant ideal: a non-racist, non-sexist future for a nation apparently determined to remain divided. At his release, after almost three decades in jail, he could have pursued narrow interests; the world would have supported him. Instead, he publicly embraced reconciliation and social justice. Nelson Mandela was determined to free not just black South Africans, but all South Africans, from prejudice. And it was in daring to do the unexpected, in weathering criticism from friends, in reaching out to enemies and in acknowledging the most humble that his greatness was revealed.
