If wishes came true, the world would actually be a really dull and uninspiring place. Whether we're wishing for money or love or happiness or health or any of the other multitudes of things people wish for, if we were to receive all of these things, what would we wish for? What would we strive for? What would we dream about? What would we hope for?
A wish is sacred and beautiful, but if it always came true, would we even bother to wish anymore? What would be the point? Even in adversity or despair, wishing creates that light at the end of the dark tunnel. Maybe that wish will be granted, maybe not, but at least it provides what is really important, even in times of struggle: hope.
So, if wishes came true, we would no longer have anything to wish for. And I believe that would be a sad place indeed.
