IN vain I see the morning rise, 
In vain observe the western blaze, 
Who idly look to other skies, 
Expecting life by other ways. 
 
Amidst such boundless wealth without, 
I only still am poor within, 
The birds have sung their summer out, 
But still my spring does not begin. 
 
Shall I then wait the autumn wind, 
Compelled to seek a milder day, 
And leave no curious nest behind, 
No woods still echoing to my lay?
Henry David Thoreau
