George Eliot said this quote

Wishes are held to be ominous; according to which belief the order of the world is so arranged that if you have an impious objection to a squint, your offspring is more likely to be born with one; also, that if you happen to desire a squint, you would not get it. This desponding view of probability the hopeful entirely reject, taking their wishes as good and sufficient security for all kinds of fulfilment.
