To improve is to change; to be perfect is to change often.

Perfect solutions of our difficulties are not to be looked for in an imperfect world.

Nothing is perfect on the human stage.

I believe that in the end that it is kindness and accommodation that are all the catalysts for real change.

It was ANC policy to try to educate all people, even our enemies: we believed that all men, even prison service warders, were capable of change, and we did our utmost to try to sway them.

I'm a catalyst for change. You can't be an outsider and be successful over 30 years without leaving a certain amount of scar tissue around the place.
