How to get rid of the fear of the audience?
Understand the reason for your performance. Honestly answer yourself the question: "
What am I performing for? Is it an obligation that I just have to fulfill, or am I presenting my findings, and this is a very important and personal step for me?"
Take more time to prepare. Immerse yourself in the topic: read additional literature, watch videos, and talk to professionals to build a solid knowledge base around your topic.
Try to take your mind off your fears and concentrate on how great it is to speak, that it is a rare chance to say something to people, and if you are given it, it means you are worth it, your knowledge is valued, and your opinion is respected.
