Most people are a little nervous when they have to stand in front of a group and deliver a speech. Some people are really nervous. Practice won’t entirely get rid of nerves, but it will do a lot to make the process of delivering a speech less painful and scary.
Craft an excellent speech. (Or hire a speech writer to craft one for you)
Practice. Practice. Practice. Read your speech out loud. Change the words that cause you to stumble. Read your speech in front of a mirror. Practice looking up from the page. Sometimes, printing the speech with extra large font helps with this.
Deliver your speech to a friend or loved one. Ask for feedback. Repeat Step. 2.
