The speaker of this poem is Robert Frost himself. He is thinking about a career decision he made many years ago. He had to make a choice between seeking a secure profession which would enable him to live in comfort or to devote him to poetry and live a simple life close to nature. Same like the poet, many of us don’t know whether to trust our instincts and go ahead with the pursuit of our dreams. Frost chose to devote his life to his poetry. The poet does not appear to regret the choice he made, but he sounds wistful in the last as if he wishes he knew what his alternate life would have been like if he had taken the other road.
