The easiest way to answer this question is through practices. A lot of practices! I can give you some tips to study the beauty of public speaking right here, but remember: 50% of the presentation you deliver should be effective and the way you deliver it is the most important thing from public speaking. When you practicing, identify your speaking style to get comfortable and discover your uncomfortable. When you know your personal style, then it would be easier to get an effective public speaking.

Before you start the presentation, you need to give attention to your physical appearances; hands, eye contact, facial expressions and your body posture because this is the first thing the audience see from you. The outfit you wear is important as well as your vocal inflections while delivering the speech or presentation.

Next, preparing yourself mentally. Know your audience to deliver it in the best way, and plan for unexpected developments if the audience wants something or asking questions to you. I know the feeling of nervousness in front of small or big audiences, but most things in life are mental! Walking into a situation psychologically ready is a huge achievement but need a lot of practices. 

Lastly I want you to know that a good public speaking won’t happen overnight because it is a learning curve. Public speaking is a long time study and it is not instant. Practice with your friends, coach and look out for famous speakers on internet and learn from how they behave when they deliver the speech. You don’t have to be perfect, you just need to improve! Good luck for all of you, and as a closing I want to recommend you a platform to improve your personal growth, life lessons and educational course from Growth Central VC.
