Consolation, Jane Austen

Depend upon it, you see but half. You see the evil, but you do not see the consolation. There will be little rubs and disappointments everywhere, and we are all apt to expect too much; but then, if one scheme of happiness fails, human nature turns to another; if the first calculation is wrong, we make a second better: we find comfort somewhere— and those evil-minded observers, dearest Mary, who make much of a little, are more taken in and deceived than the parties themselves.

- Jane Austen, Mansfield Park (written between 1812 and 1814; Published July 1814).
