I like the little article below too:

hear hear!!!The second step to confidence is faking it. Even though you may be unnerved in your mind, if you walk out on that field as if you own it and nobody can take it from you, you will give off an aura of confidence. If you tell yourself that you are the best fighter out here, and no body can beat you this day, you slowly start to listen to yourself. I think the phrase is "fake it, till you make it". If you continue to make yourself carry those shoulders high, and have no fear in your eyes or your mind, eventually those traits will become apart of you and you will be all those things.
