人生因為不能重新來過，所以我們永遠會去想像，如果當初選擇了另一條路，如今又將會是怎樣的景況？ 

美國詩人 羅勃.佛洛斯特：未竟之路
Robert Frost's poem: The Road Not Taken

Two roads diverged in a yellow wood,

And sorry I could not travel both.

黃樹林裡兩條小路，但我不能同時走過。

And be one traveler, long I stood,

And looked down one as far as I could
To where it bent in the undergrowth;

孤獨旅行的我佇立良久，望著其中一條直到盡頭，看著它消失在叢林深處。

Then took the other, as just as fair,

And having perhaps the better claim,
Because it was grassy and wanted wear;

Had worn them really about the same,

Though as for that the passing there.

於是我選擇了另一條路，也許更值得我大步前走，因為綠草如茵未被踏過，若曾經有人從這裡走過，路的狀況應會有所不同。

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.

那天早晨枯葉鋪滿小路，沒有腳步踏過的痕跡，原先那條路改天再走吧！明知小路會通向另一方向，但我懷疑是否還能回到原處。

I shall be telling this with a sigh,

Somewhere ages and ages hence:
Two roads diverged in a wood,

and I took the one less traveled by,

And that has made all the difference.

許多年以後，也許在某處，我會輕輕地歎息：「黃樹林裡兩條小路，而我，選擇了人跡較少的一條，使得一切變得多麼不同！」
