Opportunity

Master of human desires am I.

Fame, love, and fortune on my footsteps wait,

Cities and fields I walk; I penetrate

Deserts and seas remote, and, passing by

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.

- John James Ingalls

 And here are two other quotes I like about opportunity (something I always hope I have the wisdom to recognize and the courage to follow):

"Opportunity is missed by most people because it is dressed in overalls and looks like work." 
-Thomas A. Edison

"Opportunity is not a lengthy visitor"
- Stephen Sondheim, "Into the Woods"
