Hear What You Want: Wordsworth Argues Against Resolution?

The poem "Resolution and Independence" ends with its speaker resolving not to allow himself to fall into melancholy while in the mist of nature after meeting the old man, saying "God, be my help and stay secure; I'll think of the Leech-gatherer on the lonely moor." Wordsworth seems to me to argue that the speaker's resolution at the end of the poem is not because of the absolute truth or merit of the old man's words and demeanor, but because the speaker chooses to listen to him, and could just as easily forget this resolution. My evidence for this lies in a connection the speaker makes from the ol man to something he says much earlier in the poem. In stanza three, lines 17-18 the speaker says "I heard the woods and distant waters roar; Or heard them not." He later says in stanza 16 lines 107-108 "His voice to me was like a stream Scarce heard." Though he then asks the old man to repeat himself, and upon hearing the old man's story of trials and perseverance admonishes himself for being sad over so little, the point is made. Just as he chooses when to hear the stream he chooses when to hear the old man, and though he is hearing his words and seeing his struggles fresh in his mind's eye now, the speaker could easily soon forget these things and allow himself to return to his sad spirits if he so chose. This fits with the poem as a whole, which cycles between joyous revelation and sadness, as stated in lines 33-35 "Far from the world I walk, and from all care, But there may come another day to me - Solitude, pain of heart, distress, and poverty." There is not much resolution in "Resolution and Independence," or at least not resolution which lasts.
