The Road Not Taken (Poem)

I still remember about a decade ago when I was in the secondary school, our English teacher taught us to understand the meaning of this poem. Currently I remember back about this poem which related to who and what I do rite now. When I read back this poem. It's truly has a deep meaning even thought it just only mention about the road. The issue here is, "what if I take the other road, will it make the difference?".
"The Road Not Taken" is a poem by Robert Frost published in 1916.


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.
