Six mistakes mankind keeps making century after century, by Seneca

“Six mistakes mankind keeps making century after century:
-Believing that personal gain is made by crushing others;
-Worrying about things that cannot be changed or corrected;
-Insisting that a thing is impossible because we cannot accomplish it;
-Refusing to set aside trivial preferences;
-Neglecting development and refinement of the mind;
-Attempting to compel others to believe and live as we do.”
