Seems like a year or two of MMA has done way more for his charisma than whatever media training he's done over the years. He's a lot more natural in interviews now.
Alternatively, he’s completely relaxed here because he knows what he’s doing is genuinely good and people will support it. That’s gotta be a lot less stressful than, say, a senate hearing.
I've noticed the same thing! I think the personal confidence you build training hard MMA is a lot more empowering than the presonal confidence you build from making billions of dollars and being CEO of a gigantic company. For those of us without the money, it seems hard to believe, but people are people even when they're rich, and I've seen MMA change a lot of people in the same way.
There is something especially confidence building about training martial arts, I personally believe it adjusts our fight-flight response, which is also kicking in in social situations.
It’s not just training with other people but becoming used to receiving physical insult, it dampens our baseline fear of physical attack that we all feel in our factory default configuration.
People may not like Joe Rogan but he described BJJ perfectly: 3D chess with consequences. It is a great way to relieve stress and forces you to temporarily forget about whatever is bothering you that day.
