No child is born arrogant and seeking after power. They are always humble and have a peace about them throughout their day. But as they grow, they are being compared and challenged by society to become better than their peers at something. As they seek attention, their peace and equanimity take a hit. They spend so much useless energy that they devote to proving themselves and telling others about their accomplishments.
They thus build up their false sense of ego, and then become obsessed with promoting themselves. When circumstances change and they fail invariably along their selected endeavors, they will be forced to grieve and then fate makes them humble. Why not instead embrace humility first, for its own sake, and remain in your sense of calmness?
Nobody likes to hear about your big accomplishments at a family reunion or cocktail party. It has a habit of turning people off. It may make you and your ego feel good, but only at the expense of people around you. It is called smoke and mirrors. Let others take the credit for things and let others find out for themselves your accomplishments.
For example, if you are a high school student getting an A on a project, you will feel an instinct to brag about it. But you will only succeed in making enemies and have people speaking poorly behind your back. By making yourself feel better about yourself and others, you only set yourself up for a depressing moment later on. You have built for yourself heightened expectations, and then even higher expectations, until the inevitable failure is felt. Then not only will it bring shame to yourself, but it will bring glee from others to see you fail, since you were bragging about yourself beforehand. Stay quiet about your achievements. People will noticed them, and commend you. And the compliments will seem all the more sincere because you kept your mouth shut.
