I do have spare time and I love to read, and I love just to go to a national park and just relax and just think. But most of the time, it's swimming or talking.

I love swimming, swimming's my passion and I hope I swim until the last day of my life, so I really, really do enjoy swimming, but swimming for me is simply a way of carrying a message.

I had a dream , okay, go do a swim off Antarctica, and I'd train in Gauteng and just dive into the sea off Antarctica... You've really got to do a simulated test as best you can in South Africa before you go off.

I've got two dogs - one's a Jack Russell and she's one year old now, and I've got another dog called Kanga, and I got him from a rescue shelter, and there's nothing I enjoy more than just walking them on the beach in Cape Town. I find that very destressing and very relaxing.

Ordinary won't change the world.

Very few things which are really worth achieving come easily. Sometimes they do, but most of the time you really have to work hard and cleverly.

If you've got a problem and you multiply it by 50-million people, it becomes unsolvable, but if you've got a problem and you divide it by 50-million people, it becomes solvable.
