We do not know for certain what type of decision Frost had to make. It could have been something as complex as a romantic interest or something as simple as what to have for supper. Either way, Frost refused to be the same after the choice he made ran its complete course. I think Frost was trying to convey the fact that life is full of choices and once a choice is made, one must live with the consequences forever--regardless of the situation. Another symbol he uses is that the path was "grassy and wanted wear". In this particular sentence, wanted means lacked. He is showing us that not many people had gone down that path before and made that particular choice in their lives. .
In the beginning of the poem The Road Not Taken, Frost makes the journeyer appear to be wistful and wanting to be able to take both of the paths offered to him so he could make the best possible choice and go from there. Unfortunately Frost reveals to us that the traveler must decide to take either the well-worn path where many have gone before or the least worn path where not so many have gone before. He exhibits to us that the traveler longs to come back to this point in his life and take the other way as well, but knows that he probably will not be able to do so in his lifetime. He tells us the ending of his poem with a sigh, for somewhere down along the road of antiquity, he will remember the choice he had to make on that fateful day and then learn from either the blessings he received from that journey or from the mistakes and punishments yielded in his life. He tells us that he decided to take the path least traveled by and that that has made all of the difference in his life. Although, who can really tell, if this was the best choice made for him, since we do not know what the other choice held in store for him? In the end of the poem, he is assuming he made the correct decision, because he has had a different life since he made the choice he did.
