Whenever anybody called Nelson Mandela a saint, he would say: "If by saint you mean a sinner who is trying to be better, then I'm a saint."

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

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.

Nelson Mandela once said "I can't help it if the ladies take note of me; I'm not going to protest."
