Lately, I've been, I've been losing sleep
Dreaming about the things that we could be
But baby, I've been, I've been praying hard,
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
And my face is flashing signs
Seek it out and you shall find
Old, but I'm not that old
Young, but I'm not that bold
I don't think the world is sold
I'm just doing what we're told
I feel something so right
Doing the wrong thing
I feel something so wrong
Doing the right thing
I could lie, coudn't I, could lie
Everything that kills me makes me feel alive
Lately, I've been, I've been losing sleep
Dreaming about the things that we could be
But baby, I've been, I've been praying hard,
Said, no more counting dollars
We'll be counting stars
