Acharya Prashant challenges the conventional definition of success, which is typically viewed as the attainment of goals like fame and wealth. He argues that if your goals are dictated by external authorities such as parents, religion, society, or education, then the success derived from them is not truly yours. He explains that a goal-bound life is often a sign of being dominated by others' expectations. True living is based on intelligence and being present in the moment, where no predefined goals exist. He emphasizes that goals often emerge from a confused or conditioned mind, much like a person lacking awareness making irrational decisions.
