"Two roads diverged in a wood, and I—I took the one less traveled by, And that has made all the difference.” - Robert Frost. 

That is the last line in Robert Frost’s poem: The Road Not Taken. 

In the poem, Frost starts by highlighting there are two roads. One well-trodden while the other "was grassy and wanted wear”. He chose the none that wanted wear. 

He knew there was no turning back. 

"I kept the first for another day! Yet knowing how way leads on to way, I doubted if I should ever come back.” - Robert Frost. 

Life would have no choice but to take on a new path. A divergent road, once committed to, compounds further. There is no going back and sometimes, it feels like a trap. 

For that, the traveler need only have read a line another of Frost’s poem: A Servant to Servants. 

“The best way out is always through.” - Robert Frost. 

The hard thing is understanding the road less traveled means you can no longer catch up to those that traveled the popular one. It’s not that the roads might converge in the future. It’s that you can't know for certain. 

Of course, you can’t catch up with someone who has taken a different road. It’s like trying to compare apples and oranges. We know it’s silly. But it’s a hard realization to accept, understand and one day appreciate.
