Please comment on the final line of "The Road Not Taken," in particular analysing the use of the word "difference."

The poem is symbolically all about choice, and the choice
in particular of this speaker to take "the road less travelled by" and the way that this
is actually a major decision in his life that impacts the way that the rest of his life
will run. The final stanza in its entirety cements the symbolic significance of this
poem. Whilst the poet is literally talking about a walk through the woods and the way
that he had to choose between two roads, at the same time, the importance that this
decision is given, and the way that we are told that he will be retelling this
experience "Somewhere ages and ages hence" points towards a deeper symbolic
significance. Frost is using the paths in the forest as a kind of symbol for the massive
decisions that we must make in life at times.

The final
line therefore, in the way that it focuses on the massive "difference" that choosing one
path, or one option, over another can make, helps indicate this symbolic significance
and illustrates the theme of the poem. Our choices can make "all the difference," and
often one choice that may or may not seem very significant can have profound
ramifications on our future and where we end up.
