I started a book "Barron's 1100 words you need to know" yesterday, and I found some sentences I couldn't understand.

The whole of the paragraph is as follows.

-------
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 book are replete with so many wonders that it is often discouraging to see bright young people limit their own experiences.
-------

The parts I cannot understand are
"may very well be learning all there is to know in a very limited area" and
"that it is often discouraging to see bright young people limit their own experiences."


1. may well be learning..
Does it mean "may very well be learning that there is to know in a very limited area"?
What does "all" mean?
And why is it "in a very limited area"?

2. that it is often discouraging..
What does it mean..?
It means, if a young man reads books voraciously but all of them are in a very limited area, reading books limit his/her experience?


Actually I can't understand what the whole of the paragraph means..
