In the final stanza of “The Road Not Taken,” Robert Frost assumes a wistful tone. He imagines himself years in the future sighing and looking back on the results of his choice to take one road over another. He has chosen the road “less traveled by,” the one that is least known, and that, he says, “has made all the difference” in his life.
Let’s reflect on what this might mean. Frost is not merely sighing about a country road. As pleasant and pretty as such roads are, this poem has a much deeper meaning. There is some truth to the statement that one never knows what may lie along an unknown road. The whole poem asserts that. The speaker is faced with a choice, and he does not know what lies along either road, bad or good. He cannot see around the bend in either direction. He must choose the best he can, and he chooses the one that is slightly less traveled.
Herein lies the potential meaning of the last stanza. In this reading, the speaker takes a risk. He reaches out in a direction that fewer people have taken. He decides to be different, and he expects that this will make a significant difference in his life. He will learn more. He will have unique experiences that he would not have had otherwise. When we take a chance on the unknown, we might just open ourselves to opportunities we never dreamed possible.
Of the options available in the question, this meaning is the best choice. It is worth noting, however, that scholars often dispute the accuracy of this popular interpretation by pointing out the irony of the speaker’s final statement. You can read more on this subject at the link below.
