Glory arrives too late when it comes only to one's ashes

What we do now echoes in eternity.

Every moment think steadily as a Roman and a man to do what thou hast in hand with perfect and simple dignity, and feeling of affection, and freedom, and justice; and to give thyself relief from all other thoughts. And thou wilt give thyself relief, if thou doest every act of thy life as if it were the last, laying aside all carelessness and passionate aversion from the commands of reason, and all hypocrisy, and self-love, and discontent with the portion which has been given to thee.

Live a good life. If there are gods and they are just, then they will not care how devout you have been, but will welcome you based on the virtues you have lived by. If there are gods, but unjust, then you should not want to worship them. If there are no gods, then you will be gone, but will have lived a noble life that will live on in the memories of your loved ones.

It is the duty of men to love even those who injure them.

I, who have never willfully pained another, have no business to pain myself.

It never ceases to amaze me: we all love ourselves more than other people, but care more about their opinions than our own.
