Attitude precedes service. Your positive mental attitude is the basis for the way you act and react to people. 'You become what you think about' is the foundation of your actions and reactions. What are your thoughts? Positive all the time? How are you guiding them?
The hero and the coward both feel the same thing, but the hero uses his fear, projects it onto his opponent, while the coward runs. It's the same thing, fear, but it's what you do with it that matters.
