Little story speaks for itself.

An ambitious man set himself a goal and began to move towards it. After he reached his goal, he was satisfied. But soon he became thirsty again; although he was already set for life … no need to worry about wealth, he had plenty. He met with Greed and they became friends. So Ambition and Greed decided to set more goals and become even richer. So they did. But the thirst never went away. On their many journeys they came across many individuals whom they mostly ignored unless there was opportunity to accumulate more wealth, until one day they came across someone who had a broad smile and kind eyes, his name was Content. There was something unusual about this one. His humble abode was neat and great calm lived in it. Content had a wife; her name was Love, and also two children, twins they were; Joy was the one and peace was the other. “Are you not thirsty for more?” asked Ambition. “No, I have enough, thank you.” “How can you be happy with so little?” Asked Greed. “Oh, dear stranger, I have plenty. Look around you in this household lives contentment, love, joy and peace. Gold and silver cannot buy these. I would not trade what I have for anything this world has to give.” Ambition and greed left this extraordinary household in deep thought, somehow knowing that a very good seed had been planted in their hearts.
