Whether I interpret Frost's poem "The road not taken" ironically or literally, it is an interesting comment to choices and life direction (see poem below). I don't want to be a person who always says: I should rather have done this or that; I should have taken another road. Instead I want to look forward, knowing that I am not walking alone. And even if it may not be possible to go back, it is possible to change direction, when needed.
The road not taken
TWO roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth;
Then took the other, as just as fair,
And having perhaps the better claim,
Because it was grassy and wanted wear;
Though as for that the passing there
Had worn them really about the same,
And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on to way,
I doubted if I should ever come back.
I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I—
I took the one less traveled by,
And that has made all the difference.
(Robert Frost, 1916)
