I know a 12-year-old boy who can tell you the batting averages of every professional baseball players, but can’t recite the names of the 4 types of clouds that move across the sky.

Because he thoroughly enjoys baseball – virtually living, eating, and sleeping it – his constant involvement and immersion in the sport have led him to know a lot about it.

But he isn’t interested in clouds, so he’s never made an effort to learn about them. Regardless of how well his teachers have taught him, the concept just doesn’t hold any interest for him.
