Sickness is a hindrance to the body, but not to your ability to choose, unless that is your choice. Lameness is a hindrance to the leg, but not to your ability to choose. Say this to yourself with regard to everything that happens, then you will see such obstacles as hindrances to something else, but not to yourself.
EpictetusSo you wish to conquer in the Olympic Games, my friend? And I, too... But first mark the conditions and the consequences. You will have to put yourself under discipline; to eat by rule, to avoid cakes and sweetmeats; to take exercise at the appointed hour whether you like it or not, in cold and heat; to abstain from cold drinks and wine at your will. Then, in the conflict itself you are likely enough to dislocate your wrist or twist your ankle, to swallow a great deal of dust, to be severely thrashed, and after all of these things, to be defeated.
EpictetusIf you have assumed a character above your strength, you have both acted in this matter in an unbecoming way, and you have neglected that which you might have fulfilled.
