The mentality of a fighter is the key to success. Raw talent or technic is nothing without a good mentality. A fighters mentality affects his approach to a fight, the way he trains, how he rests, and pretty much everything. People draw these conclusions that a fighter has to be ferocious and fired up before a fight. Or that they have to be calm, cool and collected. The truth is it all depends on the person, people handle different things different ways.
I know a lot of fighters who fight because it gets them attention. They don’t take it as serious as I do or other successful fighters. In this case the fighters who fight for the wrong reasons don’t really train as hard as some who do this cause they love it. At the same time you want to have a balance. A balance between hard training and rest, between focus and not taking yourself to seriously. If all you do is train, train, and train. It doesn’t matter how tough you are you’ll get burned out on it, and you wont enjoy training or fighting as much anymore. Lots of great fighters have “valleys” in there careers. A point where they fall, lose a fight, or just lose there edge. This is the defining moment wether you fight through or accept defeat. This is the part that tests your mind.
