"The Road Not Taken" is one of Robert Frost's most famous poems. It is comprised of four stanzas, each with five lines and each adhering to the same rhyme scheme: ABAAB. The poem has been very much thought over by critics, who have questioned the meaning of the road, the idea of the journey, and what is represented. However, Frost himself suggested that the poem was simply about a literal occurrence that took place when he was out walking with his friend, the Welsh poet Edward Thomas, who was always, according to Frost, indecisive in terms of choosing a route to take.
The speaker in the poem describes coming to a place in a "yellow wood" where one road turned into two forks. The traveler is sorry that he can't take both routes, so he stands there for a long time, looking down the paths to try and discern which would be the best one to take. Having looked a long while down one path, he eventually takes the other, "just as fair," because it appears to be ever so slightly less well-worn than the other—but the speaker makes clear that the difference is minimal.
The speaker says that he told himself at the time that he had left the other route "for another day," but that in his heart he suspected he would not have a chance to come back and try it again. He then says he may one day be telling this story to others "ages and ages hence" and that determining that having taken the road "less traveled by" has "made all the difference."
