'The Road Not Taken'

In The Road Not Taken, by Robert Frost, the choice made by the narrator to take the road less traveled is symbolic of the choices one makes in life and their consequences. The two roads symbolize something much greater than literal roads, they symbolize two major paths that one has to take, and cannot turn back on. The narrator states, "Two roads diverged in a yellow wood,/ And sorry I could not travel both" (1-2). The narrator can only choose one road, or one path in life, he cannot fall back and return to the other. Like any decision in life the narrator reflects on what he has done and if it was the correct choice. He says, 

"I doubted if I should ever come back./ I shall be telling this with a sigh/ Somewhere ages and ages hence:/ Two/ roads diverged in a wood, and I,/ I took the one less traveled by,/ And that has made all the difference." (15-20).

The narrator took the "road less traveled", the more difficult and tougher choice in life. However it has been rewarding and gratifying to him, it "has made all the difference". The choice the narrator makes is unknown. One might speculate that it is Robert Frost, expressing his life through poetry and his risky decision to become a poet. Clearly Frost benefited from his poetry, so perhaps, though his use of figurative language, Robert Frost symbolized the roads as the decisions he has made in his life that have led to himself becoming a poet.
