Everyone confuses the idea of a fighter with actual fighting. The body is certainly important. It is an instrument that needs to be fast, strong, agile and durable but the instrument no more makes a fighter than, say, picking up a brush makes a painter. The instrument is just the means through which the real nature of a person is expressed. A fighter is a fighter in their mindset. They learn to ignore setbacks, overcome obstacles, get over difficulties and focus on what needs to be done. A fighter achieves clarity of purpose when almost none is possible. He focuses when focusing is a difficult task. He carries on, when it seems that everyone else is ready to quit. If you’re not a fighter in your mind you are unlikely to ever be a fighter in your body no matter how fast, strong or agile you become.
