Acharya Prashant explains that the common desire for success is fundamentally a declaration of current failure. When an individual says they want success in the future, they are labeling their present self as unsuccessful and unworthy. This mindset creates a state of constant frustration and boredom because the person is living for an uncertain future point rather than being fully alive in the present. He emphasizes that the more one hungers for future success, the more they reinforce their current sense of inadequacy, leading to a life of tension and fear.
