Glory
Consider the stressed-out father taking his family on a week-long road trip. Without your maps, he would be trapped at a Piggly Wiggly buying Cokes for all four of his kids to pacify their intense hunger. You probably saved that dad, like, $7.19 in Cokes. How awesome is that?
Mapping comes with a serene peace of knowing exactly where you are in the world at all times. With all the map studying you'll do, you'll probably never get lost again. Talk about glorious—that alone is reason enough to become a cartographer.
