Acharya Prashant explains the deep connection between boredom, fear, and stubbornness. He notes that while life never repeats itself and every moment is inherently new, humans often fail to perceive this freshness because they are trapped in their past experiences and memories. There are two ways to view the unknown: one can either deny its existence because it is outside one's experience, or humbly accept that one's knowledge is limited. Most people choose the former out of fear, defining the new in terms of the old to avoid the discomfort of the unknown. This refusal to see the new leads to a sense of staleness and boredom in life.
