Step-by-step explanation:
The textbook suggests several strategies to handle nervousness when giving speeches. Visualizing success, focusing on communication with the audience, and being thoroughly prepared by choosing a topic you are passionate about are all recommended tactics to alleviate anxiety.
Practicing in front of a mirror to adjust facial expressions and gestures, as well as incorporating media in a way that enhances but does not detract from your message, are also advised to improve delivery and engage the audience.

Believing in your cause and choosing a topic meaningful to you will help convey authenticity and make your speech more convincing.
