Why do some people, even when they haven't done anything wrong, always feel nervous in front of authority figures, the opposite sex, or important occasions? Often, the problem isn't necessarily in the present moment but stems from psychological patterns formed during growth. A child who is exposed to a high-pressure, unpredictable environment over a long period will gradually treat "avoiding mistakes and avoiding punishment" as a survival strategy. When parents' emotions and rules lack stability, it becomes difficult for the child to develop a sense of security, and the brain habitually remains alert. In adulthood, this vigilance doesn't automatically disappear but instead generalizes to leaders, elders, authority figures, interviewers, and even attractive members of the opposite sex. At this point, it's often not the person in front of you that causes the nervousness, but the inner "judge" that always exists. People who are in this state for a long time tend to avoid risks, fear expressing themselves, and care excessively about evaluations, making it difficult to perform their true abilities at critical moments. The key to change isn't just telling yourself "don't be nervous," but rather rebuilding a sense of safety in the world through exercise, stable relationships, and continuous positive experiences, allowing the brain to gradually learn: not all authorities will punish you, and not all relationships are filled with threats.
