Acharya Prashant explains that the ego often plays subtle games when choosing challenges. Sometimes, the mind deliberately picks a challenge it cannot win so that the resulting failure provides a permanent excuse to avoid future efforts. He emphasizes that while one does not have absolute control over victory, one can certainly ensure defeat if the intention is to lose. Therefore, it is crucial to examine the underlying motive before accepting any challenge. He advises that one should always fight with the intention to win, using intelligence and discretion to choose the right battles at the right time, much like Shri Krishna advised Arjun to bypass certain opponents to focus on the primary goal.
