Last part. You’re now at the point where you pretty much have the ritual memorized.
Now, the trick is learning how to perform it well. Very nearly everyone has some
amount of stage fright; us acting types often have it even worse than most. The
trick to overcoming it is control of the nerves. Now that you’re comfortable
reciting the ritual, observe how you do it. By now, you’re not thinking about it so
much; your mouth is doing almost all the work, with the conscious mind simply making
a few connections between paragraphs. That is the right state to be in. Think about
how that feels, and learn it.
Before you go in to “perform”, do some basic acting exercises. Take a few deep breaths;
concentrate on not thinking. I think the ideal is a little light meditation, but it takes a
fair bit of practice to be able to drop into that state on demand; for now, just worry
about being calm. Being calm is far more important than anything else. If you’re calm,
you’re unlikely to screw up too badly; if you’re tense, you’re far more likely to. Some
people like to exercise the body a bit, to relax the mind; you should do what works for you.
