· In the workplace, in interest-driven settings, and in unfamiliar social situations, it is indeed necessary to restrain purposeless sharing. Talking too much easily exposes information, gives others leverage, and drains energy.
· Gossip, complaining, lecturing, showing off, and being overly intimate too soon are mostly negative-return idle talk; the less, the better.
· “Opening the mouth scatters vital energy; moving the tongue gives rise to trouble” is not a strict scientific conclusion, but it reminds people to say less nonsense and conserve energy, which has practical value.
What needs correction:
To reduce the purposes of speech to “making people happy, getting people to do things, and making oneself money” turns relationships into pure instruments. Much genuinely useful communication brings no immediate benefit: sincere sharing builds trust, emotional expression gains support, casual conversation reveals opportunities, and discussion collides ideas. In intimate relationships, if every sentence asks “What benefit does this bring?”, it will push people away.
A more stable principle is not “say nothing unless it brings benefit,” but:
- Say less nonsense in interest-driven settings; keep sincerity in intimate relationships.
- Do not gossip, complain, show off, or lecture others on how to live.
- Before important words, ask: Is it true? Is it necessary? Is it kind? Is now the right time?
- The desire to share can remain, but choose the right person, the right occasion, and keep boundaries.
- Listen first, speak later; draw fewer conclusions; avoid being too intimate too soon.
So this passage is suitable as a defensive communication guideline, not as a guideline for all of life. Guarding the mouth is guarding one’s fortune, but guarding it too tightly will also shut relationships and opportunities outside the door.
此言有防身之效，然若奉为言谈之全部准则，则失之过狭，近于市道。
所赞同者： 职场、利益场、陌生社交之中，诚宜收敛无目的之分享欲。“吉人之辞寡，躁人之辞多”，话多则易露底、授人以柄、耗神。八卦、抱怨、说教、炫耀、交浅言深，多为负收益之闲话，少说为妙。“开口神气散，舌动是非生”虽非严格科学之论，然劝人少言废话、保存精力，亦有现实之益。
所须修正者： 若谓说话只为“让人高兴、让人办事、让自己赚钱”，则视关系为工具矣。许多有用之交流，当下未必见利：真诚分享以立信，情绪表达以得支持，闲谈之中或见机会，讨论碰撞以生想法。亲密关系中若句句问“有何好处”，反使人远。
更稳之原则，非“无利则不言”，而是：
- 利益场少说废话，亲密关系保留真诚。
- 不说八卦、抱怨、炫耀、教人做人。
- 重要之言先问：真乎？必要乎？善意乎？此时说合适乎？“时然后言，人不厌其言。”
- 分享欲可有，然须择对象、看场合、留边界。
- 先听后说，少下结论，少交浅言深。“交浅而言深，君子所戒。”
故此言可作防御性沟通之准则，不可作全部人生之准则。守嘴以守运，然守之太死，亦将关系与机会拒之门外。“修辞立其诚”，诚不可失；“言多必失”，多亦当戒。二者相济，乃得其平。
