4. Use Only Data and Visuals
When you are trying to persuade an audience to believe in your ideas, you should use only data and visuals that support your messages. The concept of persuasion is about changing or reinforcing the attitudes and beliefs. You are dealing with emotional people and that means applying reason to your argument.
If you spend the time preparing to be persuasive and deliver a powerful presentation, your authority will be known. Authority comes with confidence and without confidence persuasion disappears.
