Two roads diverged in a wood, and I–
I took the one less traveled by,
And that has made all the difference.
Wonderful advice and so poignant. But actually, if you read the whole poem, what we take from the quote isn’t what the poem was saying. Earlier in the poem it says
Though as for that the passing there
Had worn them really about the same

Robert Frost was poking fun at his friend who would obsess over what fork to take in the path as they walked when in reality the choice made no difference.
And “that has made all the difference” is poking fun at self justifications of our actions; congratulating ourselves for doing something not really worthy of accolades.
Still the top three lines do seem like insightful advice. Of course what is really needed is insight into when choosing the road less traveled is wise (or at least a sensible gamble) and when it is less traveled for very good reasons.
I do believe we far too easily slip into habits encouraged by the well worn path most people take. And therefore think balancing that tendency with at least considering the road less traveled more often is wise. But I actually like that when you read the full poem it really isn’t saying that.
