Right before you speak, refocus your brain.
You are the most nervous right before you speak. This is the moment where your brain is telling you, “Everyone is judging me. What if I fail?” And it is exactly at this moment that you can refocus your brain. Remind yourself that you are here to help your audience. Be firm with your brain. Tell yourself, “Brain, this presentation is not about me. It is about helping my audience.” Over time (usually between four and six presentations), your brain will begin to get it, and you will become less nervous.
