Metaphor and Fallacy

I couldn't help but feel that there could be a quite different way to read the metaphor as life being a journey. It has probably got to do with one's attitude to what a journey actually is. If one sees a journey as a means to reach a goal this Watts' reading might be true, but I rather hold the odd perspective that a journey will take you some places that aren't preconceived. At least I would not undertake the effort if it only takes me some place I had an exact idea of. A journey could be so much more than a means to some end. And a way to understand what it could mean to expect the unexpected.
