There is a mythological story about a king in the Hindu scripts. The king had conquered all the kings and became the king of the kings. Then he heard from his guru that all the triumphant kings of the past had written their names on a mountain which was made for this purpose only by the creator.

So, the king reached there and found a big mountain. There he saw names of old kings written all over it. He couldn't find an empty space where he could have written his name. So, he started shouting which attracted a sage who told him to remove one of the name and write his own. He was astonished to heard it. He told that it is not fare. The sage told that it is not as bad as the kings of the past had also done the same. It was a big surprise for him. Now he realised that it is not a big matter if he had achieved something as many in the past had done it and he even don't know the name of them. So, his own name would be deleted one day by someone in future. It opened his eyes and he started living a simple life.

Moral of the story: It is not a big thing to achieve something as anyone can achieve better than it. One should not be arrogant and imagine oneself as the supreme. Nature can destroy anyone and anything. Our achievements are nothing compared to the vastness of the universe. Some people become arrogant when they become rich but richness has no limit. One may have one millions, other may have ten millions and some others are billionaires. I have seen people with money to lose their wisdom. They should not forget that others are richer than them.

So, living with a healthy and balanced mind is essential to lead a happy life. It can change the world and make it happier for everyone.
