The speaker expressed that he thinks both paths are good, but the speaker is just one person who cannot travel down two different roads at a time.

The speaker later expressed that he would keep the first road for another day knowing how way leads on to a way, he expressed his doubt on coming back. This means that the speaker chose the first road, and he will not change the course of his sojourn to travel the other road.
