Acharya Prashant addresses a question about the doubt that arises after making significant life choices, such as selecting an engineering branch after getting into an IIT. He explains that the level of self-awareness at the time of clearing exams like the JEE and appearing for counseling, typically around the age of 17 or 18, is usually very low. The decisions made at this age are often not well-informed because students neither know what a particular branch holds for them nor do they know what they truly want in life. These choices are frequently based on external factors like JEE rank, previous years' allotment patterns, advice from others, and what is trending, such as Computer Science being an evergreen favorite. The decision is dictated by rank, not inclination. The speaker points out that the education system, from classes 9th to 12th, is focused on preparing for exams with specific books, but nobody teaches about life. This results in terrible levels of self-awareness. Consequently, even those who get into sought-after branches often find themselves wondering what they have done, with many later pursuing different fields like management. He advises against regretting past choices, like the branch selected two years ago, as that has already happened. Instead, one must learn from this experience for the many future decision-making events that are far more important, such as choosing a job or higher studies. Acharya Prashant emphasizes that these future decisions must be born out of inner light, not from the darkness of ignorance, social considerations, trends, or peer pressure. The choice of branch is important, but it does not determine one's entire life. The choices made upon leaving the campus are far more critical because life outside is harsh and unforgiving, where bad choices are not corrected but feasted upon and exploited. To decide rightly, one must first know the decision-maker—oneself. He urges students to be very choosy about the real things in life, to be prepared to wait for the right opportunity, and not to accept something unworthy out of desperation or fear of missing out.
