Hope, by Emily Dickinson.

I had to recite this poem in front of my English 101 class. It's one of her more well-known poems. Brilliant.
 

“Hope” is the thing with feathers -
That perches in the soul -
And sings the tune without the words -
And never stops - at all -

And sweetest - in the Gale - is heard -
And sore must be the storm -
That could abash the little Bird
That kept so many warm -

I’ve heard it in the chillest land -
And on the strangest Sea -
Yet - never - in Extremity,
It asked a crumb - of me.

 
(E.D.)
