You are not alone if the thought of speaking in public scares you. Speaking in public is genuinely scary for most people, including many who seem very calm outwardly. Presenting or speaking to an audience regularly tops the list in surveys of people's top fears - more than heights, flying or dying. But don't worry - your audience wants you to succeed. They're on your side. They're glad it's you up there and not them. All you need to do is follow the guidelines provided by Educationbelt on Presentation Skills, and everything will be fine.
As the saying goes, don't try to get rid of the butterflies - just get them flying in formation. So, how do you settle the butterflies and get them flying in formation? Good preparation is the key to confidence, which is the key to you being relaxed, and this settles the butterflies.
Good preparation and rehearsal will reduce your nerves by 75%, increase the likelihood of avoiding errors to 95%.
