When I was still in school, I used to act and do improv theater. I had wild stage fright when I first started - I am on the autistic spectrum and an introvert. The way I got through that was by making the all of the mistakes, saying all the dumb things on stage, forgetting lines, messing up blocking, etc etc. After doing enough of them I realized that it didn’t kill me, my family still loved me, and my friends still liked me.

Fear sucks. If the goal is important, push through.
