Do not waste what remains of your life in speculating about your neighbors, unless with a view to some mutual benefit. To wonder what so-and-so is doing and why, or what he is saying, or thinking, or scheming -- in a word, anything that distracts you from fidelity to the ruler within you -- means a loss of opportunity for some other task.

In the end, what would you gain from everlasting remembrance? Absolutely nothing. So what is left worth living for? This alone: justice in thought, goodness in action, speech that cannot deceive, and a disposition glad of whatever comes, welcoming it as necessary, as familiar, as flowing from the same source and fountain as yourself.

When you are annoyed at someone's mistake, immediately look at yourself and reflect how you also fail; for example, in thinking that good equals money, or pleasure, or a bit of fame. By being mindful of this you'll quickly forget your anger, especially if you realize that the person was under stress, and could do little else. And, if you can, find a way to alleviate that stress.

...the infallible man does not exist.

Now departure from the world of men is nothing to fear, if gods exist: because they would not involve you in any harm. If they do not exist, or if they have no care for humankind, then what is life to me in a world devoid of gods, or devoid of providence? But they do exist, and they do care for humankind: and they have put it absolutely in man's power to avoid falling into the true kinds of harm.

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

Take away your opinion, and then there is taken away the complaint, 'I have been harmed.' Take away the complaint, 'I have been harmed,' and the harm is taken away.
