The "Selfish" Networking Skills of a Social Master:

1. Ingenious self-marketing: adept at weaving personal strengths (such as connections and abilities) into seemingly casual complaints or anecdotes, can accurately establish the persona of being "popular and capable" in just the time of a meal, quickly sparking others' interest in forming connections.

2. "Predatory" networking: Once they enter your circle, they will establish close connections with your friends at an astonishing speed (even surpassing you), often using your private matters (unintentional remarks) as conversation starters to get closer to others, making you feel crowded out.

3. Short-term collaboration tool: This ability to quickly showcase value and attract connections makes it very easy to find partners. Newcomers are drawn to their extensive network, hoping to gain information or resources, while they use this to expand their network like a snowball effect.

4. The Trap of Deep Connections:

Value exchange is paramount: Connections are vast but extremely utilitarian. Benefits are exchanged only with those who are 'useful', making it difficult for those without value to get close.

Information is a chip: your privacy and matters are just their "talking points" and "information asymmetry", which can be sold at any time to someone they consider more valuable in exchange for favor. Confidentiality is zero.

Used instead: Those who hope to gain benefits by attaching themselves to others often become stepping stones and pawns for their ascent.

Ironically, the truly candid and helpful "firewood personality" is often excluded for being too blunt, while the calculating egoists continuously benefit from the games of networking.

Core: These people are efficient short-term connectors, but dangerous long-term partners. Their core is the maximization of their own interests, and connections and information are merely tools.
