How far a person can go often doesn't depend on how much they know, but on how they use language to define the world. Language is not only a tool for expression but also shapes the boundaries of cognition. People who habitually say "There's no way" or "It's too difficult" will gradually stop searching for possibilities; whereas those who habitually ask "Is there another path" are more likely to discover opportunities. The true gap between people is often not IQ, but the openness of their language system. Because how you describe the world determines how you understand the world; what you repeatedly emphasize will eventually become how you live.
