How to convince anyone of anything within 10 seconds !

Persuasion skills are the ability that some possess and enable them to change the behavior, convictions, and behavior of a person or other group toward a specific individual or group of individuals, events, or ideas. Persuasion is often accomplished by conveying a specific message, feelings, information, or thinking to the other person, or a combination of this.
Persuasion may depend on a set of psychological tricks, and not only on the message that you want to communicate, but people do not pay attention to that, although it will be beneficial to candidates or marketers of a particular product, or even applicants to a job or missionaries in a religious group. This is why people fail to persuade others of what they have or fall victim to a fraudulent persuasion process. Therefore, your understanding of these strategies is important whether you are the one who practices persuasion or with whom persuasion is practiced.
Convince the other of what you want to say before you say it. What you do in the beginning affects what you will offer people after, for example, if you appear as a trustworthy person in front of a group of listeners, then this manipulates what you have not yet said, and trust in your words before they hear it.
