The nature of poet’s choice remains ambiguous. It is subjective. One can know the right or wrong in retrospect. Here, one gets a feeling that the poet loves the difference made by the choice so probably his choice is right.

Once a choice is made, the consequence happens. The poet has already chosen a path and faced a whole new world. He is contemplating that point where he was standing in front of the wood and thinking and now the choice has brought all the difference.

The poet is saying that he chose one way to enter and kept the other one for some other day and he knows that in this world one doesn’t know which way will lead to where so one may find other ways from one way and he is sure that there is less chance of taking the other path some other day.

The symbolic interpretation is that a choice can be made arbitrarily but its result is clearer to us only when we think about it in hindsight. So we must not regret any decision which we make.

The poem is a realistic description of a wood and two roads diverting in it. The first line gives us the image of the wood which is yellow. The visual description of the roads makes us imagine how ‘grassy’ it is. There is also an image of leaves on the diverging roads.
