George St-Pierre is regarded as one of the best MMA fighters of all time. The following quote is GSP talking about his mindset going into a big fight...

"Your body can dictate your mind, so when I walk to a fight, a lot of times I am scared.  

 

I’m scared to death.  I have a lot of doubts about myself.  I’m afraid to fail.  I’m afraid to be humiliated in front of everybody.  

 

But what happens, I act like it’s impossible for me to fail and that my victory is a certainty.  

 

So as I am walking to the Octagon, and I act with confidence, my body takes over my mind and I become confident for real.

As I am walking, I see the change in my mind, and when I reach the Octagon, I am a different person.  I am a very confident person."
