How does Browning try to convince the reader that attempt is more important than the ultimate achievement of experience in life in the poem "The Last Ride Together"?

The speaker in “The Last Ride Together” is not necessarily the same person as the poet. The speaker addresses the poem to his lover as he tries to convince her to take one last ride with him before they part. This ride may literally be a horseback ride, but it has often been interpreted as metaphorically representing sexual liaison. Although the lovers will no longer be together, the speaker is philosophical about the times they have had and reminds his mistress of the efforts he expended in winning her love. He compares romantic contests to other areas of endeavor in life. In their previous rides, he says, his spirit was opened to new ideas, which he calls regions and cities. Most efforts are unsuccessful, and most labor does not yield a product. Anticipating the goal is also worthwhile, he says; the amount that is accomplished is small when we set it alongside to what remains to do: “contrast / The petty done, the undone vast.”
