The first line I love because it's so simple. It's rejecting the narrator, so straight off we feel sympathy for the narrator, not because of anything that the narrator has told us about his life but because we see him growing beneath our very eyes, and I like that a lot.
The second line is almost a rush of strange thoughts, and I like this also. I see it sort of a "fwooosh!" An infodump of ideas confined into seven syllables. But a good infodump.
And then I love the last line. Ending the poem with something so simple is just gorgeous. And I just love it because you have this change occurring in your narrator, but at the same time this statement is so innocent, so free of any change that the change is going back, not to the angsty days of old, but the older days of love and simplicity.
So yes. I love this poem.
