If you think you control things that are in the control of others, you will lament. You will be disturbed and you will blame both gods and men.

It is the act of an ill-instructed man to blame others for his own bad condition; it is the act of one who has begun to be instructed, to lay the blame on himself; and of one whose instruction is completed, neither to blame another, nor himself.

To live a life of virtue, match up your thoughts, words, and deeds.

Do nothing in a depressed mood, nor as one afflicted, nor as thinking that you are in misery, for no one compels you to that.

You may be always victorious if you will never enter into any contest where the issue does not wholly depend upon yourself.

When we blather about trivial things, we ourselves become trivial, for our attention gets taken up with trivialities. You become what you give your attention to.
