"The Road Not Taken" by Robert Frost was not meant to be an inspirational piece. It was meant to be a piece regarding regret, and one's self-convincing that he or she has made the right choice. The very title gives a hint to this. "The Road
Not Taken". The focus is on the choice that could have been made, but wasn't. When one makes a choice between two equally good paths, and when one is "sorry [he or she] could not travel both", human psychology, scumbag that it is, will tend to saddle the psyche with "what if"s.
In words better than I could have used:
"But you yourself can resurrect it from zombie-hood by reading it—not with imagination, even, but simply with accuracy. Of the two roads the speaker says "the passing there / Had worn them really about the same." In fact, both roads 'that morning lay / In leaves no step had trodden black.' Meaning: Neither of the roads is less traveled by. These are the facts; we cannot justifiably ignore the reverberations they send through the easy aphorisms of the last two stanzas.
This poem does not advise. It does not say, 'When you come to a fork in the road, study the footprints and take the road less traveled by'. The ironic tone is inescapable: 'I shall be telling this with a sigh / Somewhere ages and ages hence.' The speaker anticipates his own future insincerity—his need, later on in life, to rearrange the facts and inject a dose of Lone Ranger into the account. He knows that he will be inaccurate, at best, or hypocritical, at worst, when he holds his life up as an example. In fact, he predicts that his future self will betray this moment of decision as if the betrayal were inevitable. This realization is ironic and poignantly pathetic. But the 'sigh' is critical. The speaker will not, in his old age, merely gather the youth about him and say, 'Do what I did, kiddies. I stuck to my guns, took the road less traveled by, and that has made all the difference.' Rather, he may say this, but he will sigh first; for he won't believe it himself. Somewhere in the back of his mind will remain the image of yellow woods and two equally leafy paths."
I suppose that my English teacher's irritation with Hallmark for twisting the poem has overtaken me a tad.
