Every person that you meet knows something you don't; learn from them.

The saying urges intellectual humility: no matter one’s status or expertise, each encounter offers the possibility of learning because other people possess experiences, skills, and perspectives we lack. It reframes social interaction from comparison or judgment to curiosity and attentive listening. In practical terms, it recommends treating everyday conversations—at work, in family life, or with strangers—as opportunities to expand one’s knowledge and empathy. The line also implies a democratic view of wisdom: insight is distributed across society rather than concentrated in a few authorities, so growth depends on openness to being taught by anyone.
