想起美國詩人羅勃‧佛洛斯特的詩The road not taken
Two roads diverged in a yellow wood,
And sorry I could not travel both......
Oh, I kept the first for another day!......
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.
