In "The Road Not Taken," by Robert Frost, the speaker has a decision to make. He comes to a fork in the road. "Two roads diverged" and the speaker is trying to decide which road to take. One road appears to be less traveled. The speaker decides to take the less traveled road and he claims at the end of the poem that the less traveled road has made all the difference in his life.
The poet wrote the poem in first person which could indicate that the speaker is the poet:
Frost wrote the poem in the first person, which raises the question of whether the speaker is the poet himself or a persona, a character created for the purposes of the poem.
No doubt, life is about choices. We have choices to make and the speaker is worried that he has made the wrong choice. He worries that he will have regrets and will be telling his story with a sigh, "somewhere ages and ages hence." He took the road less traveled by. He saved the other road for another day, and now he worries that he shall never get the opportunity to take the other road for "way leads on to way."
Life is filled with decisions. There are different roads that one can take. The speaker is torn between two roads. He takes the road less traveled by. Now, he wonders about the road not taken. He can only imagine what life would have held if only he had been able to take the road not taken. This poem is about the road the speaker did not take.
The speaker seems to be a nonconformist. He takes the road that less people traveled. He takes the road that will be lonely for less people are traveling it. The speaker has to travel alone. In one sense, this can be a positive thing for he will have less distractions.
In the end, the speaker takes the road less traveled by and claims that it has made all the difference. The reader questions whether or not the speaker took the right road. The speaker seems to be upset at having had to make a choice between the two roads. But the speaker could only be "one traveler." The speaker deliberated for "long [he] stood," trying to decide which road to take. In the end, the reader can only suppose that the speaker took the right road for he claims it has made all the difference:
Two roads diverged in a wood, and I,
I took the one less traveled by,
And that has made all the difference.
