The speaker recommends arriving early to practice with any equipment and materials. Rehearsing the speech is important to feel familiar and comfortable with the content, which reduces nervousness. To be successful, the speaker should visualize themselves speaking loudly, clearly, and confidently, as this self-image will influence the actual performance. Audiences want presentations that are interesting, stimulating, informative, and entertaining. Nervous energy should be harnessed and turned into vitality and enthusiasm. Gaining experience through multiple presentations builds confidence, which is key to effective speaking.
