The ultimate potential of life depends upon the art of discovering one's talent and making the most of it. Nature has given everyone some kind of talent. However, most of the people do not recognize their true talent. They keep themselves busy in a futile attempt of making comparison with others better in certain aspect of life and develop an inferiority complex, which lead them to feel useless.
Comparing oneself with others is a root cause of the sense of feeling useless. The moment you compare oneself or give attention to the idea of being compared with someone more successful in life, then the sense of feeling useless occurred in your mind. By making comparison you waste your mental as well as physical energy at such a level that you do not have enough energy available to concentrate on positive aspects of life.
Hence you should learn not to compete with others because you will always find someone better than you in any given aspect of life. According to the law of nature, the collective potential of everyone is the same, but no two persons have exactly the same talents. So there is no scope of true caparison left in life.
Therefore, you should learn to make use of your own unique talent and try to live with you limitations comfortably. No one is going to compete with you for being you. If you do not give importance to being yourself by discovering your unique talent and making use of it, then you degrade your reputation in your own eye and develop the sense of feeling useless.
Finally, life is a gift to cherish. Figure out your own gifted talent and make the best use of it. Do not waste your energy and complicate all things in life by making comparison. You are destined to enjoy the beauty of life by the virtue of your own unique talent. Be yourself and make use of your talent.
