     I'm going to show you how to be a public speaker that everyone wants to hear. Surprisingly most people

are extremely scared of public speaking. I think it really boils down to the fact that most people don't get it

taught in school or by their parents. I'm going to show you how you can look like a great speaker if you apply

these techniques.

     If you really want to be liked by people as a speaker, telling stories is probably the best asset(资源) you can

have. It is a very effective tool of communication that dates back to the cavemen paintings on walls. Human

beings relate to stories they hear. You can use these stories to get a specific feeling out of your audience. You

can tell a story where you emphasize how"heroic" you are and people will feel that way. You can also use a

story to really get people involved in the speech because it is interesting. Throwing facts at people, no matter

how accurate, isn't going to make people like you as a speaker.

     You should definitely have a call to action and a purpose to your speech. You don't want to end up being a

speaker who just talks about stuff for the sake of talking. There needs to be an underlining purpose for

everything said and a call to action on this purpose. If you're talking about hurricane relief, you have to have a

purpose of what you're trying to get across and let people out there know how they can start helping. This is

how to be a public speaker that everyone likes.

      Having some visual effects can really make you succeed as a great public speaker. If you're talking about

poverty in a third world country, a picture is going to have a much bigger impact than any word.
