Question

why does the poet say " and that has made all difference

Answer 1

Explain "and that has made all the difference."How did it make all the difference

In Robert Frost's famous poem "The Road Not Taken," the author uses symbolism to express the importance of individuality.  The road represents the course of the narrator's life. 

In this case, the narrator, reflects that, of the two paths he could have taken in life, he chose to follow "the one less traveled by," and he believes "that has made all the difference."  Basically, the narrator reached a point in his life when he was faced with decision to either conform to society and live a "normal" life, or to live his life in way that embraces individuality or an less conventional existence than the first path.  The road that fewer people had taken ("was more grassy and wanted wear") was more inviting to the narrator, so he made the choice to follow the path that fewer people had taken.  The narrator believes that chosing to follow the norm would have been the wrong decision.
