Sometimes it’s the little things that have enormous consequences. An old proverb has it that for want of a nail—and intermediate steps—a kingdom was lost.
The proverb came to mind in January of this year, when television screens showed the cruise ship Costa Concordia capsized on the island of Giglio, off the coast of Italy. Reportedly, the ship’s master diverged from the planned course to give passengers a closer look at the island. Obviously, the look was far too close; the rocky shore tore open the hull, and progressive flooding ensued. For want of following the correct course, the ship was lost.
