Upon Mrs.Shabana's request (you can rest at ease now :P), I'm posting my literary interpretation essay :)
Through his poem "The Road Not Taken", Robert Frost portrays the choices one faces in life by comparing life to a walk in the woods. On the surface, the poem describes a road that divided into two roads and the speaker's frustration at not being able to take both. The speaker then, after observing both roads, chooses the road 'less traveled by'. On a deeper note, though, we see more insight on life by Robert Frost.
'Two roads diverged'; Frost promptly opens his poem with the conflict: the speaker is faced with two roads, one of which he must choose, and will probably never be able to change. These roads just as easily represent the choices one faces in life. Whether in education, marriage, or simply social relations, the choices one makes are usually always irreversible. The setting of a forest also emphasizes the maze-like characteristic of choices. As Frost aptly puts it, 'way leads on to way', creating a web of choices. This makes it even more crucial to make the right choice at the beginning.
But how did the speaker make his decision? At first, Frost leads us to believe that both roads seem equally appealing and 'just as fair', but then he goes on to say the second road might have 'the better claim, because it was grassy and wanted wear'. After walking down the second road, though, the speaker again reevaluates his choice and comes to the conclusion that both roads 'that morning lay, in leaves no step had trodden black', but he had only realized that both roads seemed equally trodden after he had made his choice. These identical paths symbolize a combination of free will and fate; one is free to choose, but doesn't truly know beforehand what one is choosing between. It takes both choice and chance to determine one's route in life. Thus, the focus of the poem is not the roads themselves, but what they will lead to in the future.
'And that has made all the difference'. the difference mentioned could be one of two: either the speaker will experience a nostalgic relief by taking the second road, or regret for the same reason. The speaker himself still doesn't know which it will be since he hasn't lived the difference yet; his evaluation of the difference his choice will make is still in the future. All the speaker is sure of is that his choice will make 'all the difference'.
Robert Frost's message by "The Road Not Taken" is twofold; first, he tells us to be careful of our choices, since, once made, are irreversible. One's decisions will open up yet more choices, and one can get lost trying to find the right ones. And second, Frost highlights a common dilemma in life; no matter how carefully we make our choices, the outcome still relies partially on chance. The outcome of the speaker's choice is yet to be determined; all we can be sure of, though, is that it 'has made all the difference'.
