Frost's The Road Not Taken is actually about the road of life. The writing focus of this poem is not the road of choice, but the road without choice. The purpose of the author's writing is to deepen the theme. The poet lamented that there are many roads to choose from in life, but one can often only take one road, and there are many other roads, because life is too short to give up. The choice of life path is often accidental, because with the choice, those roads that have not been taken will be more missed and more nostalgic. Poets don't write the road they choose, but focus on lamenting the road they have no choice, which can impress readers' hearts and guide people to think more deeply about the choice of life, thus increasing the philosophical depth of poetry and deepening the theme of poetry.
It is precisely because there is no choice that there is more room for imagination and life has an unknown color. This is also the value of choice.
