The provided text introduces the Theory of Happiness, a philosophical framework that links internal tranquility to the enduring presence of love. The author suggests that while childhood joy is innate, adulthood happiness is often mistakenly tied to a specific romantic partner rather than the emotion of love itself. This misplaced focus causes people to lose their sense of peace when relationships change or life responsibilities increase. By intentionally reconnecting with the feeling of love as an independent state of being, individuals can become a self-sustaining source of positivity. Ultimately, this mindset allows one to manage high-stress environments and personal setbacks with a calm and resilient disposition.
