The essence of making money in business is not relying on effort itself, but on solving others' problems. The market doesn't care what you can do or what you like; it only cares whether you can help others solve their problems faster and more conveniently. The gap between people is not about resources or luck, but whether they stand on the "demand side." Ordinary people tend to fall into self-centered perspectives, only thinking about "what I can do," while truly successful earners always start from others, focus on specific groups, identify their most urgent and annoying pain points, and provide a direct and effective solution. Essentially, making money is about continuously amplifying the ability to "save others time, energy, and costs," turning "selling products" into "selling results," and then achieving sustained and stable income growth through repeated service to the same demand.
