Gonna go off on a rant here, but I dislike when people use this quote in isolation. It makes the poem seem like it's about individualism, that there is something great in choosing our own path - the road less travelled. When in reality if you read the damn poem both roads look the same. It isn't clear which road is less travelled. The guy is having a hard time picking one. But he thinks in the future he's going to look back at this moment and claim he took the road less travelled and that is was an important decision. I'm no poetry expert, but it seems to me the poem is almost mocking the rationalizations people give for their decisions. And of course instead of picking up on nuance people read it as triumphant and affirming. Whatever.
