If you lose three or four in a row, people start talking about retirement. They are not used to this sport like they are used to tennis. If you take a look at how many times Rafael Nadal and Roger Federer lost, it's all part of the game. Soccer is no different: teams go through bad times and then rise again.
My father was a very tough guy with me and my brothers. He wanted to teach us a lot of discipline and life philosophy. As I became more interested in martial arts, he started teaching a lot of fighting philosophy and karate philosophy. While he was a tough father, he also knew when to be sweet and show a softer side.
Karate is my main martial art; that is what I train in every day. It has always been in my life. Sumo is another Japanese martial art that I got into at an early age. It is something that has helped and added to my overall stance and is a good base. It is not something I necessarily use in all my fights, though.
