Listen, your job was to learn how to handle life's events naturally. To want things without being crushed when you don't get them. To avoid things without panicking when they happen anyway. To never feel completely helpless or completely unlucky. To be free, unblocked, and unforced. To align yourself with how Zeus runs the universe. To obey that order and be satisfied with it. To blame no one and find fault with no one. To be able to say from your heart: 'Lead me, Zeus, and you too, Destiny.'
Man, your purpose (business) was to make yourself capable of using conformably to nature the appearances presented to you, in your desires not to be frustrated, in your aversion from things not to fall into that which you would avoid, never to have no luck (as one may say), nor ever to have bad luck, to be free, not hindered, not compelled, conforming yourself to the administration of Zeus, obeying it, well satisfied with this, blaming no one, charging no one with fault, able from your whole soul to utter these verses: Lead me, O Zeus, and thou too Destiny.
