Acharya Prashant addresses the common issue of why people start tasks with great enthusiasm but fail to sustain it until the end. He explains that most resolutions are driven by external factors rather than internal understanding. For instance, students often decide to study only when the exam date sheet is released, or people make New Year's resolutions based on a date rather than a genuine realization. Because these actions are triggered by external situations, they cease as soon as the situation or influence changes. If a teacher's criticism motivates a student to study, a friend's praise can just as easily demotivate them. When you are not personally present in your decisions, your resolutions cannot endure. He further elaborates that work done under influence is temporary because external circumstances are inherently unstable and changing. He uses the example of a candidate in a group discussion who is active only when speaking to impress others but becomes passive immediately after, showing no real interest in the discussion itself. Acharya Prashant emphasizes that a task can only be sustained until the end if it has no 'end' or ulterior motive. If the work is merely a means to an end, the energy will dissipate once that end is achieved or the motive changes. To illustrate this, he compares two types of runners in a park: one who runs for the joy of it and another who runs solely to lose weight. The one running for weight loss will stop once the goal is met or if they get discouraged by slow progress. However, the one who runs for the love of running continues indefinitely because the activity itself is the reward. He concludes that whether it is studying or any other pursuit, enthusiasm remains consistent only when the action arises from one's own joy and understanding, rather than being a burden carried to achieve a specific external result like exam marks.
