Some people say that in the current environment, it's becoming increasingly difficult to earn 💰. Is it because the world's 💰 has decreased? I don't think so. It's because the people and fields where 💰 flows have higher demands and standards. In the past, providing a product was enough to earn money, but now, in addition to quality products, quality service is also required. People are no longer just buying the products themselves; they also need the series of services that come with the products. Of course, in professional fields, professional services must grow in sync with the specialization.
