because it’s easier to go down than it is to climb up.

It is impossible for some people not to “go down” or give up because they do not have the same consistent source of energy through their ears to their brain that you do. The time sense extends forward more than backward. Your friend’s sense of hopelessness is a treatable condition. Appropriate exposure to high-frequency sound makes more rational, more hopeful, more energetic behavior possible and creates more integrated self-concepts. If you could back up your words with an invitation to a “music bar” where brains could drink in healing sound, your story would have a different ending!
