“Kindness is unconquerable, so long as it is without flattery or hypocrisy. For what can the most insolent man do to you, if you contrive to be kind to him, and if you have the chance gently advise and calmly show him what is right...and point this out tactfully and from a universal perspective."
-Marcus Aurelius
This reminds me of a quote from Thomas Carlyle
"A great man shows his greatness by the way he treats little men."
