The educated person knows things, but the wise man knows people. It is not possible to know life without knowing the individuals that make up the world.
A man is not a thing – he’s a combination of certain good and bad traits that make him distinctive among his fellow men. Each one is an influence for good or evil, whether we realize it or not.
