Nelson Mandela told Oprah in 2001 that being humble is most important:
"If you are humble, you are no threat to anybody. Some behave in a way that dominates others. That's a mistake. If you want the cooperation of humans around you, you must make them feel they are important — and you do that by being genuine and humble. You know that other people have qualities that may be better than your own. Let them express them."
