I could not prove the Years had feet— 
Yet confident they run 
Am I, from symptoms that are past 
And Series that are done— 
 
I find my feet have further Goals— 
I smile upon the Aims 
That felt so ample—Yesterday— 
Today's—have vaster claims— 
 
I do not doubt the self I was 
Was competent to me— 
But something awkward in the fit— 
Proves that—outgrown—I see—
Emily Dickinson
