what doubt did the poet have in his mind
the poet was standing at a path where he had to make a decision on choosing a path which was worn about the same. he finally decided to choose the second path and thought of coming back to the first another day. but he was doubtful if he ever came back to the same path. this is a metaphor of our life when we have to make decisions. these two paths are the good and evil of life. hence the poet chooses the path of good and becomes successful.
hope this helps!!
