Self-doubt has been an integral part of the human experience, and has been extensively discussed and portrayed in various forms of literature. Indian epics are replete with instances of even gods and principal characters grappling with self-doubt. For instance, in the Ramayan, when Hanuman is asked to cross the ocean to reach Lanka, he stands at the seashore bewildered. He forgets that he has all the power to leap across the ocean and has to be reminded of his capability. In the Mahabharat, Arjun is consumed with anxiety about doing the right thing on the battlefield of Kurukshetra. Even after the Pandavas emerge victorious, Yudhishthir falls into depression and requires constant reminders of his duties as a king.
In the Yog Vasishta, Rishi Vishwamitra takes Ayodhya prince Ram to Sage Vasishta for guidance in dispelling his depression and doubts about preforming his duties. The struggles and moments of uncertainty of the main characters, often presented as powerful, wise and all-knowing, are described in great detail throughout the texts. It is unfair to expect humans to always be confident when even gods seem to experience self-doubt.
However, self-doubt cannot be justified by insufficient preparation or knowledge. We need to be comfortable with expressing our lack of confidence, as this would demonstrate true confidence and reassurance, even in professional settings, and help us stay humble and grounded.
