For the longest of times I have known this poem. It has helped me when I've felt so low that I never thought I'd get up again. It was Nelson Mandela's favourite poem too so we are in good company.
Several years ago it was part of a movie and it was recited by Morgan Freeman who, with his deep soulful voice, gave it more gravitas and made it come alive even more. Here it is for anyone who needs reminding that they are the one in charge and it will hopefully give you the strength you need.
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.
