Zelda La Grange said this quote

[Mandela] had believed all his life that you are very much in control of your own body, and, in the process of healing, your mind had to be stronger than the medicines applied. You also had to have determination to get better.

~ Zelda La Grange

To test a man's character, give him power. Once people have power they will always reveal themselves.

~ Zelda La Grange

[Mandela] subsequently used words that never left me: 'Because you hold a particular position, doesn't mean that you are more important that anyone else. Your time is not more valuable that anybody else's time. If you are late you show that you have no respect for another person's time and therefore no respect for other people because you consider yourself to be more important.

~ Zelda La Grange

It is of vital importance to [Mandela] to be courteous and grateful at all times, as we never know whether we will have the opportunity to thank people or pay respect whenever they have been good to you.

~ Zelda La Grange
