Who really said it
Smart people learn from everything and everyone; average people from their experiences; stupid people already have all the answers
Socrates wrote nothing down, so anything of his has to come through Plato, Xenophon, Aristophanes or Diogenes Laërtius. This line is in none of them, in any translation. It also does not read like a translation from Greek: it is a three-part motivational structure — smart / average / stupid — of a kind that belongs to modern business writing, not to a fourth-century BC Athenian. We could not find a first appearance, an author, or even a date. What we can say for certain is what it is not.
