  What does the poet promise himself, though he can't keep his promise?      or Was the poet able to travel on the road he had left for another day?          

Answer:

                  The poet promised himself that he would come back some other time and take the often travelled road, Though he knows, in his heart, that he won't be able to keep his promise because a decision, once taken, can't be changed, as one decision leads to another.
