Reading Wisely
The youngster who reads voraciously, though indiscriminately, 
does not necessarily gain in wisdom over the teenager who is more 
selective in his reading choices. A young man who has read the 
life story of every eminent athlete of the twentieth century, 
or a coed who has steeped herself in every social-protest novel 
she can get her hands on, may very well be learning all there 
is to know in a very limited area. But books are replete with 
so many wonders that it is often discouraging to see bright 
young people limit their own experiences.
