A fighter, a real strong fighter, should always look dignified and calm, and I believe that any expression of aggression is an expression of weakness. A strong person will not be nervous and will not express aggression towards his opponent. He will be confident in his abilities and his training; then he will face the fight calm and balanced.
I never said I wanted a 'happy' life but an interesting one. From separation and loss, I have learned a lot. I have become strong and resilient, as is the case of almost every human being exposed to life and to the world. We don't even know how strong we are until we are forced to bring that hidden strength forward.
