Whether a person is truly mature does not depend on age, education, or social status, but on whether they have completed the transition from relying solely on external evaluation systems to establishing an internal cognition and value system. The education and social rules we receive from childhood often use grades, performance, wealth, and status as benchmarks; these external indicators indeed promote material development but also easily lead people into a continuous pursuit of fame and fortune, and after brief satisfaction, repeatedly experience emptiness and anxiety. When a person gradually realizes this, they will begin to build their own understanding framework internally: no longer placing happiness entirely on external evaluations, but being able to interpret experiences and confirm their own values, thus maintaining stability and composure in uncertain environments.
