"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."
