In "The Road Not Taken," how did the traveller choose between the two roads in the forest?

If we read this wonderful poem carefully, it is clear that
the way that the speaker makes his decision between the two roads is that he opts to
follow the road that loooks as if it was less travelled upon than the other. Note how
this second road is described in the second stanza:

Then took the other, as just as
fair,

And having perhaps the better
claim,

Because it was grassy and wanted
wear;

Though as for that the passing
there

Had worn them really about the
same.

Note how the road is
described as being more "grassy" and how it "wanted wear," pointing towards the way that
this road looked like it had not been used or travelled upon much. However, having said
this, the third stanza suggests that both roads are pretty much the same, so the speaker
opts for the road that, to his eye, looks less travelled, though we as readers could
suggest that there is little to choose between them.
