Acharya Prashant addresses the issue of nervousness during public speaking by explaining that the fear is not about the act of speaking itself, but about the presence of an audience. Through a series of questions, he demonstrates that one would not be nervous speaking to a wall because no one is watching. This reveals that the nervousness stems from the "public" aspect of public speaking, specifically the fear of their comments and judgments. The speaker identifies the root of this nervousness as the tendency to seek validation from others to determine one's own worth. He points out that since you know yourself better than anyone else, you are in the best position to assess whether you are good or not. The problem arises from a learned behavior of trusting others more than oneself in matters concerning one's own being. This dependency on others for self-worth is the fundamental cause of all nervousness; the more you depend on others, the more you will be afraid of them. Acharya Prashant advises that this dependency must be dropped. He distinguishes between external matters, where it is appropriate to listen to subject-matter experts like doctors or electricians, and the internal matter of one's own being, where only you are the expert. He suggests accepting feedback on external things, such as the quality of one's speech, as objective information without taking it too seriously. However, if someone comments on your being, stating "you are not good enough," you should not listen, as your being is not an external thing subject to their judgment. He concludes by reassuring the questioner that she is already good enough. While actions can always be improved, the self should not be seen as something that needs improvement, as this cultivates an unnecessary feeling of inferiority. It is crucial to not allow others to interfere in matters where they have no say, especially concerning your deep, intrinsic value. Do not let others make you feel small or big.
