If it wasn’t for being bullied, Georges St-Pierre might’ve never become a two-division UFC champion and arguably the greatest mixed martial artist of all time.

“Growing up, I was a kid that lacked a lot of confidence. I believe that’s why I was picked on,” St-Pierre told Burt Watson in the latest “Legend 2 Legend” episode. “Like in nature, predatory animals always hunt the weakest in the group. I was one of those (kids). I didn’t have good self-confidence, and the way I used to carry myself is much different than the way it is now. I used to walk, look down, shrug my shoulders. It showed in my demeanor, and I think that’s the main reason I was getting picked on.”

St-Pierre said he was 7 when he started karate training. After a few years, he noticed a change in his demeanor.

“Martial arts, of course, taught me self-defense, but it also taught me confidence, that confidence is a choice,” St-Pierre said. “I changed the way I was carrying myself. When I shook someone’s hand, I was looking at him in the eyes. When I talked to someone, I looked at him in the eyes. I didn’t shrug my shoulders and look down anymore. I was walking straight with some kind of confidence.”

That confidence carried St-Pierre throughout his teenage years. The rest, as they say, is history.
