Distinguishing different perspectives begins with understanding choices and consequences.
This poem is often misinterpreted because of the line, "I took the one less travelled by," to mean that the author specifically made a choice few others are willing to make.
You must however, consider the following lines:
"Then took the other, just as fair,
...had worn them really about the same."
"both that morning equally lay
In leaves no step had trodden black."
Frost isn't really saying that he made a tough choice that few others had been willing to make. He is simply acknowledging that life is most often defined by choices that can't be remade, by opportunties that will only come once. It is only possible to go down one path, using your one perspective to make the choice.
Perhaps another person, with a different background would have chosen the other path. Either path presented an equal option, your unique perspective will ultimately decide if the choice was a good one or a point of regret.
