I will persist until I succeed

I will persist until I succeed.

I was not delivered into this world in defeat, nor does failure course in my veins.
I am not a sheep waiting to be prodded by my shepherd.
I am a lion. And I refuse to talk, to walk, to sleep with the sheep.
The slaughterhouse of failure is not my destiny.

I will persist until I succeed.
