How does the speaker in 'walking around" resolve the conflict inside him?

The speaker tries to resolve the conflict inside him by describing every hideous thing he sees as he walks down the streets, through the office buildings, everything he observes, he takes in. And then he processes what he has observed, only to realize that he doesn't want to end up like these miserable people and situations. This is his way to convince himself to man up and face the conflict inside of him.
