Hello. You forgot to say that this question is about "Mississippi Solo."
Answer:
The author often uses the pronoun "I". In addition, he uses words that refer to his life in the past, where he reflects on things that happened.
Explanation:
A memoir is one in which a narrator tells things about his own past, showing experiences he has had throughout his life.
We can see that the lines shown above are a memoir, because the narrator uses the pronoun "I" several times, showing that he is talking about something that happened to him. In addition, the presence of verbs in the draw frame reinforces the idea that he is telling things that have already happened. He is writing what is in his memory, being then, a memoir.
I'm not too sure but a guess would be that pain is temporary, and that sooner or later the pain would go away. The quitting part I would think means I quit trying to forget to take away the pain maybe.
