Hovel and mart and palace, soon or late
I knock, unbidden, once at every gate!
If sleeping, wake—if feasting, rise—before
I turn away. It is the hour of fate,
And they who follow me reach every state
Mortals desire, and conquer every foe
Save death; but those who doubt, or hesitate,
Condemned to failure, penury, and woe,
Seek me in vain and uselessly implore;
I answer not, and I return no more.
