The world is full of magical things patiently waiting for our wits to grow sharper.
He that wrestles with us strengthens our nerves and sharpens our skill. Our antagonist is our helper.
If you get the dirty end of the stick, sharpen it and turn it into a useful tool.
As the traveler who has once been from home is wiser than he who has never left his own doorstep, so a knowledge of one other culture should sharpen our ability to scrutinize more steadily, to appreciate more lovingly, our own.
