Generally we are occupied either with the miseries which now we feel, or with those which threaten; and even when we see ourselves sufficiently secure from the approach of either, still fretfulness, though unwarranted by either present or expected affliction, fails not to spring up from the deep recesses of the heart, where its roots naturally grow, and to fill the soul with its poison.
