The Little Virtues

Thought for the day, from The Little Virtues, by Natalia Ginzburg (translated by Dick Davis):

As far as the education of children is concerned I think they should be taught not the little virtues but the great ones. Not thrift but generosity and an indifference to money; not caution but courage and a contempt for danger; not shrewdness but frankness and a love of truth; not tact but love for one’s neighbor and self-denial; not a desire for success but a desire to be and to know.

Personally, I have an advanced degree in Caution. Is it too late to go back and take Courage 101?
