UFC welterweight champ Georges St-Pierre hasn’t lost in more than five years and is seen as one of the top three pound-for-pound fighters in Mixed Martial Arts. With a resume boasting wins over opponents like Nick Diaz, Carlos Condit, Matt Hughes, Jon Fitch, and B.J. Penn it would be easy to assume St-Pierre has shaken any type of jitters when it comes to his endeavors inside the Octagon. However, as GSP recently revealed, he enters every fight with fear in his heart.

“I’m scared. Before a fight, I doubt myself. I’m scared,” St-Pierre admitted to Inside MMA.

“I try to be confident, but deep down inside, I’m afraid. I’m afraid to get knocked out, afraid to get humiliated, afraid to have done all that work and put all that effort for nothing. That’s why I’m afraid,” he continued. “It’s not really being afraid of my opponent. I’m afraid of not performing the best. I think it’s the same fear that keeps me sharp.”

Though some competitors are driven by confidence, St-Pierre’s motivating force is apparently related to failure. It’s also clearly working given his 24-2 mark in the sport and eleven-fight winning streak.
