My friend Jack who was always working hardly so that he could earn enough to buy a car of his own. He used to say, “My life will be better when I get a nicer car.” It took him more than three years to make his dreams come true. However, Jack was not satisfied with what he has achieved. He worked even harder, hoping that he would able to buy a big house with a beautiful garden. One day, I told himself that happy is a journey, not a destination.
