Introducing myself is the hardest thing for me as well as general conversation. But I've been a pro wrestler for 15 years, and for some reason, when I am in front of a live crowd with a microphone and filing any spots, the stutter leaves me for some reason. I think because there is a fight or flight mode and letting it slip is 100% NOT an option. But when I'm more relaxed and just talking in a normal setting, it is noticed a lot more. Like someone said, our brains are weird.
