I'm so nervous during presentations and meetings, how can I improve my public speaking?

You gotta breath slow, calm down, and focus before you start. When you do start try to see those people as your friends, keep your eyes on friends you have, so it would be easier to maintain eye contact and feeling a bit adjusted while talking.

First of all, you don't forget that everybody can make mistake .Spectator is also a person like you.

Preparation is the key !! Take your time and let the people in front of you know what you have researched on !!

Practice in front of friends or family and even the mirror. Writing down what you want to say in point form on cards can help too.

Everyone feels nervous when they speak in public. So remember that it is always natural to feel a little nervous about going on stage. I think everyone is different but the following could help a lot: Practice in front of a mirror over and over. Find out where the weak spots in your presentation are and focus on them. Practice in front of friends, family, mentors. Remember that people don't go to bed at night thinking about your presentation and all the mistakes you made. Little mistakes are common and accepted. There is nothing wrong with fumbling over your words a little. If you are feeling a little overwhelmed, there is nothing wrong with taking a slight pause for a second, deep breath to regain composure.

Practice makes perfect! As a public speaker, I had to overcome the same nervousness. I found it helpful to speak in front of family and friends... as well as in front of a mirror!

Maybe you can try performing speeches in the mirror. It might sound weird, but talking to yourself in bathroom, in the mirror can help a lot. I know this from my own experience.

Practice in front of a mirror, make a video, or just recite a certain number of times until you are totally comfortable!

Practice. Practice infront of people you feel comfortable with, like your parents or housemates or siblings. Then when you've practiced, just imagine you're doing it just to those people when you're presenting.

Remember that the listeners are there for the information, not a fashion evaluation. Remind yourself of what you have to do afterwards so you have a reference point for distraction that relaxes you.
