quasi bonis et fortibus et magno animo praeditis ulla sit ad rem publicam adeundi causa iustior, quam ne pareant inprobis neve ab isdem lacerari rem … - Cicero

The enemy is within the gates; it is with our own luxury, our own folly, our own criminality that we have to contend.

Beatus autem esse sine virtute nemo potest

Everyone has the obligation to ponder well his own specific traits of character. He must also regulate them adequately and not wonder whether someone else's traits might suit him better. The more definitely his own a man's character is, the better it fits him.
