Nelson Mandela also spoke about how, as a human being, he's made mistakes.

Nelson Mandela was just a human being, a person like other people, and everyone relaxed. Within a minute, that sort of thing about the leader and the lead, the gap was closed, and that's a rare thing.

Currently, we allow our political and business leaders to get away with murder. Now is the time to change that. We need direct liability for those who are destroying our future and this planet. We need fast, profound and systemic change. History only moves forward when courageous people get up and act. That's why I support this citizens' initiative to recognise ecocide as the crime it is.

I first met Nelson Mandela when I was in my late 20s, in 1993. I was helping facilitate an African National Congress (ANC) workshop to plan its media strategy. I went down to meet him for the first time and you know me I got stupid... I just choked. I said, "Hello Madiba, it's a real honour to meet you," and I couldn't get another word out.

In Durban, where I was born and grew up, and all over Africa, Nelson Mandela was a hero! Now he is a hero to the world.

[Nelson] Mandela was very keen not to be understood as an exceptional person.

I've come across a lot of people in my life who talk about poverty and talk about the poor, but you rarely have a sense that it matters to them to the point at which they will be willing to sacrifice something.
