I was asked to give a speech on the Everest swim, and during the Everest swim, I changed. I changed as a person, I honestly did. That mountain changed me, and I gave a speech about it for nine minutes.

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.

I'm one of the lucky people that, my job is my passion, is my hobby. I hope this doesn't sound arrogant: I truly feel that this is what I'm meant to do, to swim and to talk about protecting the environment, my two passions.

Mount Everest is a very spiritual place, it's a beautiful mountain.

I think every child in every country, not just South Africa, every year should go to a national park, and it should be part of their basic curriculum.

You shouldn't be able to do a swim at the North Pole, it should be frozen over.

Ordinary won't change the world.
