We live in a world where advertisement has us mesmerized. You can't drive down the street without seeing a display of something that you do not already have. And that will always be, because even the richest person won't ever have it all.
We see pictures of places we have yet to travel to, things we don't own and qualities we will never posses.
We have all that we need but it's the things we want that drag us down. The person next to you will always have something you don't, and you them.
That is the source of the dark cloud that creeps in, hovers over our lives and causes we the people, who have so much, to feel poor and inferior.
