Every habit and faculty is confirmed and strengthened by the corresponding actions, that of walking by walking, that of running by running. - Epictetus

30. *Appropriate actions are largely set by our social relationships. In the case of one’s father, this involves looking after him, letting him have his way in everything, and not making a fuss if he is abusive or violent. “But what if he’s a bad father? ” Do you think you have a *natural affinity only to a good father? “No, just to a father.” Suppose your brother treats you badly. In that case, maintain your fraternal relationship to him. Don’t think about why he behaves that way but about what you need to do to keep your will in harmony with nature. No one else, in fact, will harm you without your consent; you will be harmed only when you think you are being harmed. So make a habit of studying your social relationships – with neighbors, citizens, or army officers – and then you will discover the appropriate thing to do.

Você deve se submeter à disciplina, comer de acordo, não tocar em doces, treinar debaixo de rigores, numa hora fixa, no calor e no frio, não beber água muito gelada, nem vinho, a não ser quando receber a ordem de fazer isso; você deve se entregar completamente ao seu treinador assim como o faria com o seu médico e depois, quando chega a hora da competição, você deve se arriscar a se machucar e algumas vezes ter a sua mão deslocada, torcer o tornozelo, engolir um bocado de areia, algumas vezes ser fustigado, e junto com isso tudo, ser derrotado. Quando você considerou tudo isto muito bem, então ingresse numa trajetória de atleta, se você ainda o desejar.

It is not the events but our viewpoint toward events that is the determining factor. We ought to be more concerned about removing wrong thoughts from the mind than removing tumors and abscesses from the body.
