I'll tell you what this song is about.
I've probably listened to it for over 100 times now, first hearing it 5/6 years ago.

It's about aiming high - having those hopes and dreams, those desires to make others and yourself proud and happy. But - you fail, and continue doing so. People say that's life, but is it? What if it's constant failure... Asks Jason Walker in this masterful piece of music.

Missing way too much - missing a loved one? Probably not. Missing on happiness, on pride, on achievement - that's what he's referring to. When it happens incessantly, he "knows he's gonna fall down", because it always happens. How do we as humans continue to try when all we do is fall down? It's hard.

He doesn't want to hear the sound of losing what he never founds = failure. He doesn't want failure, and he never found success. Not again... he says. Not again.
