Неожиданное понимание⁠⁠2

Craig, добрый день!

Когда-то давным-давно читала стихотворение Роберта Фроста (Robert Frost) "The Road Not Taken". Тогда я не поняла смысл последней фразы, но благополучно про это забыла. И сегодня вы спровоцировали вспышку памяти =)

Вопрос насчет последней фразы "And that has made all the difference." - она означает, что именно этот выбор круто изменил его жизнь (стал поворотной точкой), или что разница в итоге была только в том, как выглядела та дорожка в лесу, а в остальном не было никакой разницы?

Вот полный текст, чтобы не искать:

Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth;

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,

And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on to way,
I doubted if I should ever come back.

I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I—
I took the one less traveled by,
And that has made all the difference.
