Despite what I had acchieved, I don't for a moment think I am any braver or better than anyone else. This is how I attempt to explain what gives me the stregnth to do what I do; when that thunderbolt of an idea first hit me and inspired me to row across oceans, it filled me with a sense of purpose so strong that it overcame my fears. Even when boredom, frustration, fatigue or despair threatened to overwhelm me, it was that powerful sense of purpose that kept me going.

So let's raise the tone of the debate. Too often at the moment we look like schoolchildren squabbling over a toy - our most precious toy, the Earth. And the danger is that as we pull in opposite directions in our global tug of war, the Earth will end up broken - or at least unable to sustain human life. That is the worst case scenario - or maybe, from the Earth's point of view, the best.

The bigger the challenge, the bigger the sense of accomplishment when you get to the end of it.

I'm not claiming to be anything out of the ordinary. I am not especially big or strong or brave or intrepid.

My advice is don't keep asking yourself if you can do something. Just get out there and do it. You can really surprise yourself.

"Stepping outside your comfort zone is supposed to feel uncomfortable because we're in new and unfamiliar territory. Being uncomfortable is a sign of success, NOT of failure! So if we are uncomfortably outside our comfort zones, then than means we are growing!!! And THAT is cause for celebration!" (modified from a passage in Roz Savage's "Rowing the Atlantic")

I am a rolling stone, never in one place for very long.
