Who was the speaker of the poem the blind boy?

I found the poem to be very poignant and thought-provoking. Poet is definitely an optimist. Looks at life as a glass that is half full, not half empty. Teaches us to be mindful of the blessings we have and not be thankless or moan about what we don't have. He seems to be in control of his destiny especially as he says "my day or night myself i make"; it sounds like he is in charge of his destiny. He does not want anyone to pity him, and he certainly does not let the lack of eyesight be an impediment to his enjoying life. Buoyant spirits and a positive attitude are to be admired and the boy not pitied for his impaired vision. A very uplifting poem to be read whenever we feel less fortunate and despondent.
