God provided us everything in order for us to survive in this world. But, naturally, men always want satisfaction. They still need more to be happy. We cannot evade this thing as a human. Even though, we already have that kind of thing that we want to have but, as time goes by, we will reject it because of some more things that is still existing in this world which is more than wonderful to compare it to a thing that you had, that you did not discover yet. Everything in this world is changed. So there is a possibility that we want something new and more.
