I would compare it to an actor. I drive myself into the character that later on is in the ring.

I never fought in my life outside of a ring.

I learned in my Ph.D. the discipline I needed to be successful. Most boxers are not that disciplined. They have talent, but the self-organization - the ability to schedule yourself and your priorities - is lacking. My studies were about the control of training on both the psychological and the physical side.

I would say that Roger Federer is pretty amazing. And Manny Pacquiao - he's such a tiny, little lightweight guy, but the way he fights makes people so excited.

From nothing to everything is a long way, from everything to nothing is one stop.

If he goes down, he is to get up, and continue to fight, until I finish the process.

My brother is a doctor and he will take care of post-traumatic stress. I think he'll do it for free.
