Struggles only move forward when decent men and women step forward and say, 'enough is enough and no more.'

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

Sandy was a climate change warning. Obama must now take the stage and fulfil the promise of hope the world needs.

I think even though he [Nelson Mandela] was feted and praised as he was, he always was at pains to say, I'm a human being.

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.

Nelson's Mandela own sense of himself was a very humble reading, [different] from how the world read him. And, quite often, you had the sense that he was not comfortable with all the accolades that would be.

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.
