"The best thing for being sad," replied Merlin, beginning to puff
and blow, "is to learn something.  That's the only thing that never fails.
You may grow old and trembling in your anatomies, you may lie awake at
night listening to the disorder of your veins, you may miss your only love,
you may see the world about you devastated by evil lunatics, or know your
honour trampled in the sewers of baser minds. There is only one thing for
it then -- to learn.  Learn why the world wags and what wags it.  That is
the only thing which the mind can never exhaust, never alienate, never be
tortured by, never fear or distrust, and never dream of regretting.  Learning
is the only thing for you.  Look what a lot of things there are to learn."
