Hundreds of years ago, there was a king who has thousands of sq. km of land under his rule but he was never happy because he was envied by many of the other people and kings of other regions. He was surrounded by a number of enemies and had no contentment in his life.

One day, when he was passing through a jungle with his soldiers and other courtiers, he saw an old man with shabby clothes sitting beneath a tree, beside a house of wood and leaves. He saw that the old man was very calm and relaxed. He asked him," Hey! I am the king, but I never stay relaxed as you even in this worst condition, why?"
    The old man replied," I am happy because i am having a simple life. I have nothing which i can loss or which can be stolen, so I am unafraid. I don't have extra money or any sort of thing from which the people get envied of me, that's why I am so relaxed and in contentment, "he continued, "On the other hand, you have plenty of money and properties that's why you have so many people who are jealous of you. You Have every thing but you don't have such a contentment and The King was impressed by the old man and offered him to become his minister but the old man refused and said, " If I will become your minister, many other people then tried to replace me and they would start evil plan against me, so I am happy with my simple but contented life, thanks for your offer."
  The King went away after saying, "I have every thing but in fact nothing, because i don't have contentment."
