A Poem by John Keats

When I have fears that I may cease to be 
  Before my pen has glean’d my teeming brain, 
Before high-pilèd books, in charact’ry, 
  Hold like rich garners the full-ripen’d grain; 
When I behold, upon the night’s starr’d face, 
  Huge cloudy symbols of a high romance, 
And think that I may never live to trace 
  Their shadows, with the magic hand of chance; 
And when I feel, fair creature of an hour, 
  That I shall never look upon thee more, 
Never have relish in the faery power 
  Of unreflecting love!—then on the shore 
Of the wide world I stand alone, and think 
Till Love and Fame to nothingness do sink.
