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

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

Sometimes we set boundaries for ourselves in life, or even worse, we allow others to do so. In many cases, these boundaries are just in our mind and need to be pushed away.

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.

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 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.

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