“When another blames you or hates you, or people voice similar criticisms, go to their souls, penetrate inside and see what sort of people they are. You will realize that there is no need to be racked with anxiety that they should hold any particular opinion about you.” 

― Marcus Aurelius, Meditations

“Here is a rule to remember in future, when anything tempts you to feel bitter: not "This is misfortune," but "To bear this worthily is good fortune.” 

― Marcus Aurelius, Meditations
