No "mantra" per se but here's how I view stage fright: I'm a musician/entertainer, it's just what I do. When I'm up on that stage, that's where I'm supposed to be. The people in that crowd (or other musicians in the crowd) aren't supposed to be up there or else they would be. Obviously I can do something they can't or they would be. They look up to me. I can't let fear or anxiety stand in the way of my purpose or why I'm meant to be where I am. You don't see a firefighter doing that. If they allowed fear to make them hesitant at all, the people inside would burn up. But no, they jump right in there & OWN IT. My motto has always been, "Ain't nothin to it but to do it!" Trust me, audiences are not there expecting you to fail, they want to see you succeed, they're rooting for you. You just gotta go up there, embrace it, & have fun. If my 1000+ gigs in my life have taught me any one thing, it's this: The more fun you are having on that stage, the more fun the crowd will have. It's automatic. And the first time you are able to just relax, let loose, & get "that reaction" from the crowd, it'll be a game changer for you for life and before you know it, you"ll be as comfortable on a stage in front of a crowd as you would be at home in your PJs. When I take the stage, or hell, even while we're just setting up, I am always giddy-as-a-schoolgirl excited, knowing how awesome it's going to be & how much fun everyone's going to have. I'm always very thankful that I've been given such a wonderful opportunity to be where I am & I always let em know; by thanking everyone for coming out AND by making them have fun because I am. The moral is this: Smile, have fun, be confident & friendly, project an attitude of gratitude & you can never go wrong. And also (as if this comment isn't already long-winded enough), mistakes? Oh yeah, you're gonna make em. We all do. No matter how much we practice no human is immune to em. But if you learn to just blow past em & laugh em off, your audience will too. I GUARANTEE IT.
