Sometimes, it can actually be better to speak less. Evidence: doomscrolling short videos on social
media is popular to human hedonism. Well, in reality, people are drawn to the
unknown, and having lots of information publicly available means fewer
would be interested in being close to you.
E.g., governments kept the Epstein files secret for a long time. And
also, listening to others (and taking note of what they say) can make
you gain information, while speaking can potentially distribute unwanted
information to others. I also heard that people will trust you less if
you overexplain, because it signals low confidence to the point that you
need lots of information to try to convince the listener.
