Why I’m nervous in front of public and how to overcome it?

I can see why people are afraid of speaking in front of a group. You're up there alone. All of those eyes are fixed on you. Their ears are tuned to every word you say. You feel vulnerable. No place to hide. That feeling is called nervous. When you are invited to speak in public, you are surrounded by people who want to hear you. They asked you to speak because they believe you have something of value to say. They invested time in listening to you because they believe it will be well spent. Even an audience that opposes your point of view sees value in listening to you. Many of them may listen only to reinforce their already fixed opinions, but they still want to hear what you have to say.So when you stand in front of an audience, you're not standing in front of enemies. You are standing in front of friends, people who want you to succeed in speaking and value the information you are sharing with them. The audience admires you for having the gumption to do what most of them are afraid to do themselves. So when you stand in front of people who value and support you, you're not really alone. You're with people who appreciate you enough to listen. An audience really is a safe place to open up and express yourself. There are many ways that i know to overcome my nervousness when i'm in front of public. You can learn how to relax by doing exercises to ease your tension. Sit comfortable with your back straight. Breathe in slowly, hold your breath for 4 to 5 seconds, then slowly exhale. Apart from that, you must know your audiences, materials as well as become familiar with the room itself. If possible, greet some of the audience as they arrive and chat with them. It is easier to speak to a group of friends than to a group of strangers. From the materials aspects, if you are not familiar with your material or are uncomfortable with it, your nervousness will increase. Practice your speech or presentation and revise it until you can present it with ease. Become familiar with the place in which you will speak is also important in decreasing your nervousness. Arrive early and walk around the room including the speaking area. Stand at the lectern, speak into the microphone. Walk around where the audience will be seated. Walk from where you will be seated to the place where you will be speaking. I really hope with my suggestions here on ways to overcome anxious feeling in delivering good speeches in front of public in the near future.
