The Road Not Taken (Robert Frost)
"Yet knowing how way leads on to way,
I doubted if I should ever come back."
Time does have that way about it. Of the Frost poems assigned this is the one I am most familiar with, and it ceases to dull with each new read. The poem retains a relevance to life; people are always choosing a path; sometimes the intent is to revisit the denied course in the future, but life steps in and intent is forgoten or lost in the present shuffle.
I agree. It seems as if the narrator is already figuring on that being the case. Everything we choose in life changes us, even if just a little bit. Those changes eventually make the things we had once wanted to do seem like such a distant past, that we either no longer want to do them or we no longer feel like we can. He knows that he will change. He may want to go back now, but he knows that his future choices will change him. He may not want to return to where or how he was; he may even be unable to return.
I agree with you. Frost is being somewhat literal with this poem, but every time you read it you can get something different out of it.
