Fighter

After all you put me through,
You think I'd despise you,
But in the end I wanna thank you,
'Cause you've made me that much stronger
...
So I wanna say thank you 'Cause it
Makes me that much stronger
Makes me work a little bit harder
It makes me that much wiser
So thanks for making me a fighter

Made me learn a little bit faster
Made my skin a little bit thicker
Makes me that much smarter
So thanks for making me a fighter
