moral fiber

I think moral fiber's about finding that one thing you really care about.
That one special thing that means more to you than anything else in the world.
And when you find him, you fight for him.
You risk it all, you put him in front of everything, your life, all of it.
And maybe the stuff you do to help him isn't so clean.
You know what? It doesn't matter.
Because in your heart you know, that the juice is worth the squeeze.
That's what moral fiber's all about.
