Are you afraid of messing up in front of many people? Do you get stage frights? Calm down! Take a deep breath! Breath in, breath out, breath in, breath out.
Now, think about the purpose for which you are giving this speech. Remember that people are listening to your thoughts. They want to know about things you believe and the way you think. Don't worry about messing up. It's a human thing to do. We're all like that.
Look at the crowd. Think that you are talking to your friends. Friends are people who you share your thoughts with, without thinking about their reactions. So do that with the audience! Don't worry about the outcome. Just give it your best shot!
