Recently we finally had the opportunity to see the film Invictus. Though I knew it would be moving, it reminded me how much I loved the poem. The last two lines are written on the chalkboard I have where inspiration strikes often. Here I write my favorite quotes and remind myself daily that I can rise above any circumstance. Today, I wanted to remind you. It is worth the re-read.
Slowly.
Savor it.
Invictus
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 chance
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
Queen of the Universe 
I too watched the movie recently and was reminded of how much I like Morgan Freeman and the poem. You're right about reading it slowly. I'd go so far as to say it is best read aloud as well. Reading it aloud causes me to put emphasis on the right words, putting more meaning in it when I read it & say it than if I just read it in my head. Just my 2c worth there.
I am one of those nerds that think all poetry is best when read outloud…:)
