Lower-end clients tend to live in a defensive mindset. Their first question isn't "Does this thing have value?" but "Are you trying to scam me?" Past experiences, resource constraints, and risk tolerance have conditioned them to protect themselves first. So your sincerity cannot be directly converted into trust; it may even be interpreted as part of a sales pitch. Higher-end clients live more in a judgmental mindset. They won't easily trust anyone, but they have the ability to recognize authenticity through long-term behavior, professional competence, and consistency in details. They understand that what's truly scarce in the world is not a promise, but a person's cognition, ability, and long-term credibility. Therefore, when they encounter sincerity, they can recognize the value behind it and are willing to extend trust.
