"Being reliable" is a kind of quality for being a person, a kind of wisdom, and even more so, a golden reputation for being a person. Only by being reliable can one gain trust; by gaining trust can one obtain opportunities; by obtaining opportunities can one display and exercise their abilities; by having abilities can one create a cause - this is a crucial path for survival and development, applicable to any era. Everyone wants to stand out and accomplish something great, but whether a person can achieve greatness is determined by many factors. Among these, being reliable and trusted everywhere is a crucial foundational part, whereas a person who doesn't value credit, acts irresponsibly, and doesn't keep their word cannot possibly pass this test.
