Epictetus

Thus Socrates became perfect, improving himself by everything. attending to nothing but reason. And though you are not yet a Socrates, you ought, however, to live as one desirous of becoming a Socrates. 51.

Some things are in our control and others not. Things in our control are opinion, pursuit, desire, aversion, and, in a word, whatever are our own actions. Things not in our control are body, property, reputation, command, and, in one word, whatever are not our own actions. The things in our control are by nature free, unrestrained, unhindered; but those not in our control are weak, slavish, restrained, belonging to others. Remember, then, that if you suppose that things which are slavish by nature are also free, and that what belongs to others is your own, then you will be hindered. You will lament, you will be disturbed, and you will find fault both with gods and men. But if you suppose that only to be your own which is your own, and what belongs to others such as it really is, then no one will ever compel you or restrain you. Further, you will find fault with no one or accuse no one. You will do nothing against your will. No one will hurt you, you will have no enemies, and you not be harmed. Aiming therefore at such great things, remember that you must not allow yourself to be carried, even with a slight tendency, towards the attainment of lesser things. Instead, you must entirely quit some things and for the present postpone the rest. But if you would both have these great things, along with power and riches, then you will not gain even the latter, because you aim at the former too: but you will absolutely fail of the former, by which alone happiness and freedom are achieved. Work, therefore to be able to say to every harsh appearance, “You are but an appearance, and not absolutely the thing you appear to be.” And then examine it by those rules which you have, and first, and chiefly, by this: whether it concerns the things which are in our own control, or those which are not; and, if it concerns anything not in our control, be prepared to say that it is nothing to you.

Destroy desire completely for the present. For if you desire anything which is not in our power, you must be unfortunate

Whoever chafes at the conditions dealt by fate is unskilled in the art of life; whoever bears with them nobly and makes wise use of the results is a man who deserves to be considered good.

Let man be pleased with whatever has pleased God; let him marvel at himself and his own resources for this very reason, that he cannot be overcome, that he has the very powers of evil subject to his control, and that he brings into subjection chance and pain and wrong by means of that strongest of powers – reason. Love reason! The love of reason will arm you against the greatest hardships.

Those are the reflections you should recur to morning and night. Start with things that are least valuable and most liable to be lost – things such as a jug or a glass – and proceed to apply the same ideas to clothes, pets, livestock, property; then to yourself, your body, the body’s parts, your children, your siblings and your wife. [112] Look on every side and mentally discard them. Purify your thoughts, in case of an attachment or devotion to something that doesn’t belong to you and will hurt to have wrenched away. [113] And as you exercise daily, as you do at the gym, do not say that you are philosophizing (admittedly a pretentious claim), but that you are a slave presenting your emancipator;14 because this is genuine freedom that you cultivate.

How long are you going to wait before you demand the best for yourself and in no instance bypass the discriminations of reason? You have been given the principles that you ought to endorse, and you have endorsed them. What kind of teacher, then, are you still waiting for in order to refer your self-improvement to him? You are no longer a boy, but a full-grown man. If you are careless and lazy now and keep putting things off and always deferring the day after which you will attend to yourself, you will not notice that you are making no progress, but you will live and die as someone quite ordinary.
From now on, then, resolve to live as a grown-up who is making progress, and make whatever you think best a law that you never set aside. And whenever you encounter anything that is difficult or pleasurable, or highly or lowly regarded, remember that the contest is now: you are at the Olympic Games, you cannot wait any longer, and that your progress is wrecked or preserved by a single day and a single event. That is how Socrates fulfilled himself by attending to nothing except reason in everything he encountered. And you, although you are not yet a Socrates, should live as someone who at least wants to be a Socrates.

Después de deliberar y determinar que una línea de acción es acertada, jamás pongas en duda tu juicio. Apoya tu decisión.

Consciousness of its weakness will keep you from tackling difficult subjects.

Men are disturbed, not by things, but by the principles and notions

It is the mark of a cude disposition to spend most of one's time on bodily functions such as exercise, eating, drinking, defecating and copulating. These are the things to be done just incidentally. All your attention should be on your mind.

Geef me de moed om alles te accepteren wat niet in mijn vermogen ligt, de kracht om alles te veranderen wat wel in mijn vermogen ligt, en de wijsheid om tussen die twee te onderscheiden.

Don’t seek that all that comes about should come about as you wish, but wish that everything that comes about should come about just as it does, and then you’ll have a calm and happy life.

Remind yourself, “What upsets this person is their opinion of what has happened. Another in the same circumstance, taking a different perspective, would react quite differently.” Do not share these thoughts with the grieving person. Sympathize with them — even cry with them. Your tears will be outward, not inward.

But when he comes in thunder and lightning brandishing these things, and I show fear in response, in effect I have been brought face to face with my master, just like a runaway slave.
