The Road Not Taken

Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth.

Then took the other, as just as fair,
And having perhaps the better claim,
Because it was grassy and wanted wear;
Though as for that the passing there
Had worn them really about the same,

And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on to way,
I doubted if I should ever come back.

I shall be telling this with a sigh
Somewhere ages and ages hence;
Two roads diverged in a wood, and I—
I took the one less traveled by,
And that has made all the difference.

- Robert Frost, 1874-1963

There's an analysis here. While I was searching for this poem, I also came across a PDF presentation of the same name by Richard P Gabriel, Distinguished Engineer from Sun Microsystems, Inc. It's about the nature of future software and makes interesting reading.
