If you are pained by any external thing, it is not this that disturbs you, but your own judgment about it.

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

It's time you realized that you have something in you more powerful and miraculous than the things that affect you and make you dance like a puppet.

Hast thou reason? I have. Why then dost not thou use it? For if this does its own work, what else dost thou wish?

To no man make yourself a boon companion: Your joy will be less but less will be your grief

Be not as one that hath ten thousand years to live; death is nigh at hand: while thou livest, while thou hast time, be good.

Accustom yourself not to be disregarding of what someone else has to say: as far as possible enter into the mind of the speaker.
