How many people usually stand on the edge of everything they know and love, built on the tears of failures, built on lost dreams, striving for a better but taking every step as a success. Just to watch waves crash into everything, simply to learn that with every tear, with every failure, with every cut and with every scrape, its all sand and to find worse still the waves was also caused by your own hand. How many people stand amoung such and say, "yes I did and yes I'll pay with what I don't have, cause the sand was worth more then myself. It held all my joy and all my sorrow and even though it was all sand, it stood as a better testiment to myself then the waves which holds no sorrow and is thus not worth a momument but is worth a high price, in the sands memory."
If life went on forever, there would be no imperfect end, as everyone would eventually reach what they strive for. So there would be no memory to honor what we did right in life if there was no death.
