The poem is one extended metaphor (which shows Frost's poetic gift). It is obviously autobiographical--and Frost acknowledged that it was autobiographical. The poet is remembering how he had to make a choice of careers and life styles, which he compares metaphorically with coming to two diverging roads in the woods. He chose the one which was obviously less traveled by, judging from the fact that it was overgrown with grass and the fallen leaves had not been trodden down and blackened by many passing feet. From our knowledge of Frost's life and from his rustic poetry, we can assume that he chose a simple life that would enable him to devote his thoughts and his time to communing with nature and to creative writing, although he would have to give up the luxuries and excitement and financial rewards he might have had if he had taken the other road. He cannot help wondering what his life might have been like if he had chosen the other road at that crucial juncture in his life's journey. It is significant that even in his extended metaphor representing his life, Frost uses imagery drawn from nature. He greatly resembles the English poet William Wordsworth in getting his inspiration from nature. He also shows a strong spiritual kinship with Henry David Thoreau, the New England naturalist, poet, and philosopher.
