But, how can we know that the speaker is sincere? We should follow our hearts. The great speaker can cheat one-s heart, but it is impossible to cheat millions! We can see sincerity of the speaker in his eyes, gesticulations and emotions. Your speech will be more successful, if you are sincere!.
The next step in the successful speaker-s ladder is to become a knowledgeable speaker. One-s speech is more confident, if the speaker knows the topic. He should be sure about what he says, because it is a very important aspect in convincing the audience. Even if the speaker offers something new, he should study all positive and negative sides of his project. He should explain to the audience so that his plan is successful. He should all the ways that his speech can fail, even if possibility is less than 10% and try to find ways how to avoid them. For this speaker should study a lot! For example, most speakers read a lot of materials about their topic, even if do not use it in their speeches. Let us imagine that you were given a speech, which was written by somebody else, and your role was to just read it! You read it very impressively and everybody liked your speech. But there was a person who asked you to tell more details. If you are well educated, you could try to answer, but in most cases you would not know anything about it, and you would fail in your presentation. But, if you study a lot about your plan, you can improve your speech, answering the questions, even if the first part of your presentation was not very effective! You will convince most of people! That is power of knowledge!!!.
Once the topic of the speech is chosen, and the speaker has studied a lot of materials to confirm, he should work on his nonverbal communication. Nonverbal communication plays a great role in one-s speech. He can convince the audience by his nonverbal communication. Everybody feels pleasure when somebody smiles at him/her.
