Low-cost, high-efficiency interpersonal and survival rules:

1. Stay independent, rely less on others. Do not place your hopes on others, and do not mask your dependence or demands under the banner of "altruism." True confidence comes from your own abilities, not from others' charity or approval.
2. Break free from passive thinking, focus on real value. Don't stay stuck in the student mindset of "waiting for opportunities or arrangements." Society cares more about the value you can provide than how grand you can speak. View problems from the perspective of "value exchange": what can you give others, and why would they help you?
3. Control your expression, prioritize action over emotions. Say less empty talk, do more practical work. When lacking sufficient strength and opportunity, stay low-key and avoid rushing to show off. Focus on results, but don't completely deny emotions. Emotions are tools, but should not get out of control.
4. Reduce social costs, improve comfort in interactions. Appropriately compliment others and recognize their strengths—this is a low-cost but high-return social approach. You don't have to be overly strict with others; often going with the flow is more effective than confrontation.
5. Respect boundaries, avoid interfering with others arbitrarily. Do not easily intervene in others' choices and causal relationships, especially when they haven't actively sought help. Help should have boundaries; otherwise, it can be exhausting and unappreciated.
6. Master interpersonal rhythm. When faced with requests, think first before agreeing to avoid impulsive commitments; when refusing, be clear to prevent subsequent trouble. The warmth or coldness of relationships can have a rhythm, but do not manipulate it to the point of losing sincerity.
7. Respect others' resources and efforts. When using others' time, belongings, or help, be considerate and cherish them. Attention to detail often determines whether others are willing to continue interacting with you.
8. Avoid unnecessary disputes, focus on interests and results. When core interests are not involved, there's no need to insist on right or wrong, nor to create conflicts. Many arguments win the logic but lose relationships, which is not worth it.
