Acharya Prashant explains that boredom arises from having preconceived ideas of what is exciting. When one decides in advance that only specific activities like video games or achievement are exciting, anything else is automatically labeled as boring. He posits that boredom and excitement are two sides of the same coin; excitement inevitably leads to boredom as it fades, and boredom acts as a preparation for the next wave of excitement. To break this cycle, one must observe that excitement is not just excitement, but excitement plus boredom. He suggests remaining unaffected even in the middle of excitement, recognizing that the 'movie' of life will eventually end.
