If I wanted to know, for example, how many stars where in the milky way, how old those giant heads on Easter Island were, most of you could find that out right now, without even standing up. And yet if I've learnt anything for nearly twelve years now dragging heavy things around cold places, it that true, real inspiration and growth only comes from adversity and challenge, from stepping away from what is comfortable and familiar, and stepping out 

into 

the unknown.
