A passage that enlightens: "The greatest function of money: it ignores anyone, it completely isolates anyone. The end of making money is for peace, and the ultimate goal is to stay away from the crowd. High-end communities, business class, VIP lounges, luxury suites, all are about escaping the noise, because places with many people often come with noise, demands, consumption, and distress. With money, you gain the right to be indifferent, and with wealth, you gain the ability to be free." Schopenhauer once said: "People are like hedgehogs in winter; if they get too close, they will feel the prick; if they are too far apart, they will feel 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, scheming to curry favor, and entanglements over trivialities. This noise acts like an invisible shackle, draining our energy and time. And 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, the serenity of VIP lounges, have never just been symbols of status, but rather a "soundproof wall" built by wealth for 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 quietly, which enables him to make 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 blend 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 choose the people around us, and reserve our time and energy for ourselves and those who matter. This "indifference" is a protection of self-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." ...
