In "The Road Not Taken" there seems to be no real definitive way of choosing a path, so how would one know the right path? It seems that if there...

You are correct in saying that in Robert Frost's "The Road Not Taken" the narrator suggests that there really was no good reason to choose one path over the other. There is one phrase in particular, "Had worn them really about the same," which emphasizes that there really was little to choose between the two paths and that they did look about the same.

You are correct in saying that in Robert Frost's "The Road Not Taken" the narrator suggests that there really was no good reason to choose one path over the other. There is one phrase in particular, "Had worn them really about the same," which emphasizes that there really was little to choose between the two paths and that they did look about the same. 

The point of the poem is precisely that. Often, we are confronted with choices that seem equivalent when we are in the process of choosing, but which, in retrospect, we realize were important. There are two issues here.

The first is that fairly trivial choices might have big consequences. For example, one might choose to take the 9:30 rather than the 10:30 section of a class, an academically unimportant choice, but in that class meet a person one marries. Fifty years later, looking back, that simple choice of class time had a transformative impact on one's life. 

There is also a second, metaphorical level to the poem. Frost himself chose to be a poet rather than a doctor or journalist or lawyer. Thus we can think of the less traveled road as suggesting unusual or uncommon rather than traditional life and career choices.
