Some books are to be tasted, others to be swallowed, and some few to be chewed and digested.

It's not what we eat but what we digest that makes us strong; not what we gain but what we save that makes us rich; not what we read but what we remember that makes us learned; and not what we profess but what we practice that gives us integrity.

It is impossible to love and to be wise.
