I was reflecting on the different ways, over the course of my life, that I would get directions. Younger readers may not believe that glove compartments were crammed with maps and atlases, telling us where to go. At some point, mapquest emerged, providing a print out of where to turn right and where to turn left. That felt like great breakthrough. Now someone talks to you, telling you that in ten miles you need to take an exit. For those of us of a certain age, such guidance would have been unthinkable in earlier days. But however it comes to us, we all need direction in life.
