Thou hast seen many sorrows, travel-stained pilgrim of the world, But that which hath vexed thee most, hath been the looking for evil; And though calamities have crossed thee, and misery been heaped on thy head, Yet ills that never happened, have chiefly made thee wretched.
Martin Farquhar Tupper (1839). “Proverbial philosophy: a book of thoughts and arguments”, p.27
