Do not let anyone establish so-called "psychological advantage" in front of you, because this advantage is not inherently possessed by the other person, but is something you give away little by little when you care, feel nervous, and overthink. Others may try to overpower you with indifference, show-off, belittlement, or silence, but for these methods to truly work, you must accept them and therefore become shaken, self-justifying, or emotionally lose control. In fact, others' evaluations are just their expressions and do not equal your worth; they may be arrogant, but allowing that arrogance to affect you is your choice. The key is to reclaim the right to evaluate, and to see their behavior separately from your value: what they say or do reflects more about themselves; how you respond determines whether you are affected. Maintain a gentle detachment, avoid confrontation and self-justification, and treat the other person's emotions and stance as background rather than the center, so you won't be carried away. As long as you do not give up the right to explain, others cannot truly define you.
