You’ll be fine. If you’ve studied that much, just doing it, all will come together, behind what you’ve learned and how critical you’ve learned to be about the result. I love that line in “Shakespeare in Love” when somebody didn’t show up so they threw an entirely different person on stage. Somebody asks, “How can that work?” Answer: “I don’t know. It’s a mystery.” The show will go on.
Please, can you point me to the de-clicker you’re talking about.
