Nothing Happens to the Wise against their Expectation

NOTHING HAPPENS TO THE WISE AGAINST THEIR EXPECTATION
“Thus: ‘I shall sail unless something happens’; and ‘I shall become praetor unless something prevents me’; and ‘My business will be successful unless something interferes.’ That is why we say that nothing happens to the wise man against his expectation. We remove him not from the chances that befall mankind but from their mistakes, nor do all things turn out for him as he wished but as he reckoned—and above all he reckoned that something could block his plans. But inevitably the mind can cope more easily with the distress arising from disappointed longings if you have not promised it certain success.”
Seneca
from On the Shortness of Life
