In "The Road Not Taken," I believe the speaker of the poem took the more difficult road. He took the road less traveled by. This means he took the road with less people; therefore, his journey had to be more lonely. He took the road that the majority of people avoid.
In the road less traveld by, there would be more bumps in the road and more brush and undergrowth. There would be more obstacles as far as trees and nature's natural growth.
In my classes, I teach my students that the speaker took the less traveled road. This meant he took the road which requires much more studying. The majority took the road I call the "party" road. Students can choose the "party" road and end up without a degree. It is easy to hang out with friends and party and have a good time. It is more difficult to choose isolation that comes with hours of studying.
Truly, the less traveled road requires commitment to the journey of life called endurance. The road that requires great commitment is often a lonely road. No one likes to commit and persevere through hard work and sacrifice.
I imagine the speaker of the less traveled road felt the pains of loneliness and isolation. In the end, it will be worth all the loneliness and hours of perseverance. In the end, it made all the difference for the speaker, as it will for anyone who chooses the tougher road:
Two roads diverged in a wood, and I--
I took the one less traveled by,
And that has made all the difference.
I would agree to an extent with the above answers. Where I differ in my understanding of the poem, specifically the lines quoted above, is that, this would be told with a sigh...meaning the author himself would not truly believe that he took the road less travelled. If your read the first line six of the poem, "Then took the other, as just as fair" this tells us that both roads were of the same nature. Neither was less travelled upon than the other. Therefore; it is only in the retelling of the story later in life that the author would say that he took the road less travelled.
Robert Frost took the second road that was the road which was less opted by people.Thus,it was a difficult road.By this we also come to know about the adventurous bent of mind of Robert Frost.
