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.

Exceed due measure, and the most delightful things become the least delightful.

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.

Wisdom means understanding without any doubt that circumstances do not rise to meet our expectations. Events happen as they may. People behave as they will.

If you do not wish to be prone to anger, do not feed the habit; give it nothing which may tend to its increase.

If you would be good, first believe that you are bad.

Let death and exile, and all other things which appear terrible be daily before your eyes, but chiefly death, and you win never entertain any abject thought, nor too eagerly covet anything.
