I am finding it difficult to understand the poem "The Road Not Taken" by Robert Frost. Hence, I request you to help me out in understanding it.

Understanding a poem is simple if you understand its
summary and here is a detailed summary of the poem:-

Stanza
1

In the first stanza, the speaker, while walking on an
autumn day in a forest where leaves have changed to yellow comes across two roads. He
has to choose between the two roads diverging in different directions. He feels sorry
that he cannot follow both the roads. So in order to make his decisions about which road
to take, he pauses for a long time while and continues looking at one of the roads as
far as he can till the road curves into the bushes.

Stanza
2

In the second stanza the speaker decides to take the
other road as it appears to have been used less than the first. But then he realises
that they are actually similarly worn out. The second one that he takes seems to be less
travelled by, but as he thinks about it, he realises that they are really about the
same.

Stanza 3

In the third
stanza the speaker continues to think deeply about the possible differences between the
two roads. On that particular morning he notices that the leaves that have on fallen on
both the roads are still quite yellow and not crushed by human feet. Though the speaker
has already opted for the roads less travelled by, he wishes that one day he may
come back and walk the first road; but he doubts whether he would be able to do that
because in life one thing leads to another  and it hardly gives anyone a chance to
change tracks.

Stanza 4

In the
fourth stanza, the speaker considers how the choice he makes now will affect him in
future. He says that he would tell with a sigh that two roads diverged in a wood and he
choose the one which was less travelled and that made all the
difference
