Having the ability to make money in the long term and giving people a silly and honest feeling is the true tough character. Never think that someone who is good at making money will be a "silly and honest" or "naive and sweet" person. Regardless of how silly and honest their external appearance may be, making money is a true manifestation of a person's comprehensive strength, including intelligence, emotional intelligence, resilience, mindset, wisdom, etc. Those who can make money steadily in the long term are all tough characters. It is smarter not to show this toughness on the surface. Those who cannot make money and show so-called toughness are paper tigers without real support. They may appear clever, but they are actually "pseudo-intelligent."
