The technique I use if I ever feel this when speaking or playing gigs is to embody fully the idea that it’s not me on stage or about to go on stage anymore, I am now a character that resembles whatever that audience wants to see. That really helps because now you can hide those insecurities (that are normal) behind a persona.

I really think you are on to something. This technique is used widely by performing artists. Your comment shouldn’t be underestimated in my view.
