Read about Douglas Mawson, this poem kept him alive when suspended in an ice crevasse in the antarctic.

The Quitter
by Robert W. Service
When you're lost in the Wild, and you're scared as a child, 
And Death looks you bang in the eye, 
And you're sore as a boil, it's according to Hoyle 
To cock your revolver and . . . die. 

But the Code of a Man says: "Fight all you can," 
And self-dissolution is barred. 
In hunger and woe, oh, it's easy to blow . . . 
It's the hell-served-for-breakfast that's hard. 

"You're sick of the game!" Well, now, that's a shame. 
You're young and you're brave and you're bright. 
"You've had a raw deal!" I know -- but don't squeal, 
Buck up, do your damnedest, and fight. 

It's the plugging away that will win you the day, 
So don't be a piker, old pard! 
Just draw on your grit; it's so easy to quit: 
It's the keeping-your-chin-up that's hard. 

It's easy to cry that you're beaten -- and die; 
It's easy to crawfish and crawl; 
But to fight and to fight when hope's out of sight -- 
Why, that's the best game of them all! 

And though you come out of each grueling bout, 
All broken and beaten and scarred, 
Just have one more try -- it's dead easy to die, 
It's the keeping-on-living that's hard.

For more inspiration - read the story of Antarctic explorer, Douglas Mawson.

This poem inspired him to stay alive (when the bottom skin of his feet had frozen off)--and he found himself hanging in an ice crevasse:
