Rival

The tide is high, it's sink or swim
My only rival is within
Giants calling round the bend
My only rival is within
I won't let my demons win
My only rival is within
I will fight through thick and thin
My only rival is within
Kingdoms rise and kingdoms end
My only rival is within
This is where it all begins
My only rival is within
The tide is high, it's sink or swim
My only rival is within
