Speak the truth as you see it. But with kindness. With humility. - Marcus Aurelius

The span we live is small—small as the corner of the earth in which we live it. Small as even the greatest renown, passed from mouth to mouth by short-lived stick figures, ignorant alike of themselves and those long dead. (Hays translation)

He who does not know what the world is, does not know where he is. And he who does not know for what purpose the world exists, does not know who he is, nor what the world is. But he who has failed in any one of these things could not even say for what purpose he exists himself. What then dost thou think of him who [avoids or] seeks the praise of those who applaud, of men who know not either where they are or who they are?

...be tolerant with others and strict with yourself. Remember, nothing belongs to you but your flesh and blood—and nothing else is under your control. (Hays translation)
