Drona, the Guru of Kauravas and. Pandavas wanted to see who is the best among his students and conducted a test. He wanted them to shoot a bird in its eye with an arrow. He asked to try one after another. When they are ready he asked them what they are seeing. Only Arjuna replied that he is only the eye of the bird and nothing more. That speaks about the concentration of Arjuna and when he was on an assignment he never used to get distracted. So Drona decided to make him a great warrior and Arjuna became the dearest student of his Guru.
So it is the individual who has to resist himself from getting distracted. Then only he can become the best and always be successful in his attempts.
Believe in the existence of God the superpower.
