A passage that enlightens: "The greatest function of money: it ignores anyone, it completely isolates anyone. The end goal of making money is to find peace, and the ultimate purpose is to distance oneself from the crowd. High-end communities, business class, VIP lounges, luxury suites, all serve to escape the noise, because places with many people are often accompanied by noise, demands, consumption, and distress. With money, you gain the right to be indifferent; with wealth, you gain the ability to be free." Schopenhauer once said: "People are like hedgehogs in winter; if they get too close, they feel the prick; if they stay too far apart, they feel the cold." Most people's troubles stem from their inability to choose their social distance. In crowded places, there is inevitably meaningless small talk, endless demands, and unconscious consumption: prying into family matters, calculating flattery, and entanglements over trivialities. This noise acts like an invisible shackle, draining our energy and time. Money is precisely the key to breaking this bondage; it gives us the confidence to say "no" to people and things we dislike, the ability to actively cut off consumption, and to preserve a peaceful space. The tranquility of high-end communities, the composure of business class, and the serenity of VIP lounges are never just symbols of status, but rather "soundproof walls" built with wealth for a better life. This isolation is not about being reclusive or indifferent, but a clear choice made after experiencing the world. Just like Buffett, who has lived in the small town of Omaha for years, avoiding the noise of fame and fortune, allowing himself to think deeply in quietude, thus making precise investment decisions. He once candidly stated: "Quiet is the premise of thinking, and thinking is the source of wealth." The end of making money is peace, and peace can in turn foster growth, creating a positive cycle. The saying "only with money can one afford to be indifferent" essentially means having the freedom to refuse. When we are broke, we have to compromise for a living, forced to integrate into circles we dislike, dealing with unnecessary social interactions, and exhausting ourselves in the complexities of human relationships; when we have money, we no longer need to bow for a meager living, we can calmly select the people around us, reserving time and energy for ourselves and those who matter. This "indifference" is a protection of personal boundaries, a prevention of mental exhaustion, and the ultimate freedom granted by wealth. Thoreau wrote in "Walden": "Most of us lead lives of quiet desperation. What we call the normal life is actually a kind of habitual despair."...
