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 of hesitate,
Condemned to failure, penury and woe,
Seek me in vain and uselessly implore,
I answer not, and I return no more.
