First off, know your topic. The better you understand the topic, the easier it will be to talk about it with confidence. You know the saying: practice makes perfect. Practice in front of people you know and ask for honest feedback. Focus on your material, not on your audience. People mainly pay attention to new information — not how it’s presented. Visualise your success. Lastly, positive thoughts can help decrease some of your negativity about your social performance and relieve some anxiety.
