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.

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.

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.

We have to appreciate that we are part of nature, we must work with nature; the environment is our lifeline.

I got bored and then joined the British SAS. It was five very exciting years of my life, and then I'd always had this passion for swimming, so started swimming around the world, in some of the most exotic and distant and dangerous locations.

I was very, very lucky because I started swimming when most of the landmarks in the world had not been swum.

Ordinary won't change the world.
