If you haven't yet seen the movie "Invictus," I highly recommend it as a spirit-raising, hope-enhancing, darkness-squashing entertainment.
However, even if you don't see the movie, please read the poem from which the movie takes its title. This piece, in itself, shares a powerful message.
by William Ernest Henley
Out of the night that covers me,
Black as the pit from pole to pole,
I thank whatever gods may be
For my unconquerable soul.
In the fell clutch of circumstance
I have not winced nor cried aloud.
Under the bludgeonings of fate
My head is bloody, but unbowed.
Beyond this place of wrath and tears
Looms but the Horror of the shade,
And yet the menace of the years finds
And shall find me unafraid.
It matters not how strait the gate,
How charged with punishments the scroll,
I am the master of my fate:
I am the captain of my soul.
