"Don't go on discussing what a good person should be. Just be one."

"Everything we hear is an opinion, not a fact. Everything we see is a perspective, not the truth."

"Our life is what our thoughts make it."

"From the philosopher Catulus, never to be dismissive of a friend's accusation, even if it seems unreasonable, but to make every effort to restore the relationship to its normal condition."
