The Dream

Remember when we were kids and we had THAT dream about what we would be when we grew up: a firefighter, a policeman or Spiderman.
Then our dreams grew, as we grew up.
A successful person, a loving father, husband, or one who gives back to the community.
As we continue to grow and live life our dreams come true. But when they do, why do we continue to make our new ones? Why are we not ever satisfied?
I am not saying that dreaming is bad or that having goals is not good, but why can we not be satisfied with what our lives are?
So many people I know are searching for "the better life" or the "new" dream. I can understand someone in poverty or someone going through something bad like a life crisis or tragedy.
But why do we do it, I mean most of us have what we need and then some. Why do we have the need to make it more? Do we have something inside of us that always makes us long for more? So many people around me are searching for "more" and not that it is bad, but it does make me wonder why?
There are many people in this world are searching for their next meal or where they will lay their head. For those of us who don't have to do that, we search for more and more. Sometimes looking past what we already have.
So is "The Dream" something we should search for and wish we had?
Or is "The Dream" something we should live every minute of the day?
