Work, all our life

We work all our life, and in the end when we are too old, we realise that all was in vane.
What is life? A number of years, who run too fast, and before to realise, life go away.
There is so many great things in life, things wich we don't sawet because we work too much in order to .... Why we do that?
No matter how many things we have, we want more, and more, and never we be pleased, allways want more. But this more is for material staf, and life don't meen only that, is much more.
So here are are!  In old ages, full of regretes, with no chanse to change our past, undetstanding too late that we actualy have a single life.
