Happiness does not depend on how much you have but on what you make of what you have. It is a pity to watch the time and energy some spend to achieve things that they see others have. Being satisfied with what one has should be one's goal.
MY favorite quote is "you should be happy with what you have and nor for what we want". But sadly it is really difficult to implement this though in real life.
If everyone thinks like that then the world will be heaven because sadly almost 99% don't think like that and they even go on to fight for things that are not even there's
