Said no more counting dollars 　　We'll be counting stars 　　
Yeah, we'll be counting stars 　　I see this life Like a swinging vine 　
　Swing my heart across the line 　　In my face is flashing signs 　　Seek it out and ye shall find
　　Old, but I'm not that old 　　Young, but I'm not that bold 　　And I don't think the world is sold 　
　I'm just doing what we're told 　　I, feel something so right 　　But doing the wrong thing 　　
I, feel something so wrong 　　But doing the right thing 　　I could lie, could lie, could lie

　Hope is a four letter word 　　Make that money 　　Watch it burn 　　Old, but I'm not that old 　
　Young, but I'm not that bold 　　And I don't think the world is sold 　　I'm just doing what we're told 　
　I, feel something so wrong 　　But doing the right thing 　　I could lie, could lie, could lie 　
　Everything that drowns me makes me wanna fly 　　Lately I've been, I've been losing sleep 　
　Dreaming 'bout the things that we could be 　　Baby I've been, I've been prayin' hard
