However, right after the decision was made, the speaker doubts his/her choice just like anyone else. The speaker starts to rethink his/her decision by saying, "Oh, I kept the first for another day! Yet knowing how way leads on to way, I doubted if I should ever come back" (lines 13-15). The speaker wants to be able to take both roads, but realizes that the nature of these roads is such that he/she probably will never be able to come back to this place. This scene portrays a metaphor for a decision that changes everything. The decision described becomes one of those decision that once it is made, one can never go back. The poem ends with the speaker acknowledging his decisions by finalizing his narration with the words, "The roads diverged in a wood, and I–I took the one less traveled by, and that has made all the difference" (lines 17-20). The speaker recognizes that he took a less popular decision, and that the decision changed his life. This is a metaphor about meditating one's life. After making an important decision, one tends to sit back and reflect upon it to see how one's life has changed. Whether one's life changed for the better or the worst, the last line reminds the reader that after making that decision one succeeds or learns from one's mistakes.
In the poem "The Road Not Taken" by Robert Frost, the speaker uses vivid diction to illustrate the process we go through when making decisions. For instance, the speaker starts narrating the poem by describing a scenery of "Two roads diverged in a yellow wood" where the speaker tried to look "down one as far as [he/she] could to where it bent in the undergrowth" (lines 1, 4-5). The narrator uses vivid words such as "yellow wood" and looking at a road that "bents the undergrowth" to pull in the reader inside the poem with him/her, taking this walk in autumn and viewing these two roads that are splitting.
