There is one thing about life that everyone realises sooner or later. It has no destination whatsoever. It is all about the pursuit. There is just one thing that differentiates us as a species from any other on this planet. We have hope. We never get satisfied with what we are or have achieved, for us the journey never ends. And when it does, that is the day that you actually die regardless of when they bury you.
In essence - 'The climb is all there is.'
