The audience wants you to do well. Nobody buys a ticket hoping to watch someone freeze.

The room is not a panel of judges, whatever it looks like from behind the microphone. People came to enjoy something, and watching someone struggle is uncomfortable for them too, so they are quietly on your side from the first sentence. Even the ones who look bored are mostly thinking about themselves. Nobody is hoping for a disaster.

Before you go on, look at two or three faces and remind yourself they want this to go well. Start slower than feels natural. If something goes wrong, say so plainly and carry on, because the room forgives that instantly.
