Marcus Aurelius

You have power over your mind — not outside events. Realize this, and you will find strength.

Waste no more time arguing about what a good man should be. Be one.

If you are pained by anything external, it is not this thing that disturbs you, but your own judgement of it.

Remember that all is opinion.

The longest-lived and the shortest-lived man, when they come to die, lose one and the same thing.

Never esteem anything as of advantage to you that will make you break your word or lose your self-respect.

As for life, it is a battle and a sojourning in a strange land; but the fame that comes after is oblivion.
