The Road Not Taken - Robert Frost

I've often wonder about this poem and what it really means, because there are definitely roads that I will never go down again. As Mr. Frost points out, "Yet knowing how way leads on to way, I doubted if I should ever come back."

So having taken all these paths to reach this point (yes many of them less traveled), has it really made all the difference?

THE ROAD NOT TAKEN
by Robert Frost

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.
