- "“I will never deny the way that I’ve lived my life up until now! The path that I’ve walked until now is my pride! You want me to throw away all of the pain, regret, laughter, joy, victory and defeat that I’ve had until now!? I absolutely reject this! These two fists, this body, this soul, and my peerage, are all the treasures which I’ve obtained through fighting without ever giving up! Discarding that for false talent is something I will never do!"
