I think they all learned the obvious, even the smallest person can effect the world in the biggest ways. Tolkien added a bunch of little morals into the story, but in the words of Sir Walter Scott in the novel Ivanhoe: "His fate was destined to a foreign strand,
A petty fortress and an 'humble' hand;
He left the name at which the world grew pale,
To point a moral, or adorn a tale."
Reach high, for the stars lie hidden in your soul. Dream deep, for every dream preceeds that goal.
