People often think that understanding can be achieved through explanation, but true cognition and wisdom cannot be directly conveyed by language. Language can at most provide a structural hint, and whether a person truly "gets it" depends on whether they have experienced similar dilemmas and repeated struggles in reality. Understanding only occurs when external expressions align with internally accumulated experience. For this reason, the same sentence takes on completely different meanings at different stages of life: it's not that the information has changed, but that the conditions for understanding it have changed. Therefore, the key to changing a person lies not in persuasion, but in the cognitive restructuring brought about by their own experiences.
