In "The Road Not Taken," what reason does Frost give for choosing the path he chose?

I think part of the point of this poem is that the speaker
of the poem has to choose between two paths that appear to be pretty much the same to
him. Note how in the second stanza he starts to say that one appears to be less
travelled upon than the other, but then he goes on to contradict himself, sayikng that
both actually look identical:

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.

Frost seems keen to
emphasise the way in which both paths are, to all intents and purposes, identical. The
third stanza states that both paths had "leaves no step had trodden black." When we
consider the allegorical meaning of this poem, it becomes clear why Frost emphasises the
idnentical nature of the roads. Sometimes, we, when we have to make a decision about our
future lives between one thing and another, do everything we can, like the speaker, to
try and judge between the two decisions. We look down the path and consider whether the
path has been travelled much or not. However, with a lot of decisions, we need to choose
between two options that appear to offer no visible advantage or disadvantage to the
other. We, like the traveler, have to choose one on impulse as it were, and accept that
this choice may well have a major impact on our lives.
