There is a universal advice, what to say at the beginning?
There is no single method that is perfect for every occasion. There are dozens of entry options, and they all depend on the task that needs to be solved: for example, to actualize a problem, create an intrigue, or get to know the people in the audience better.
The classic way to start is to greet the audience, introduce yourself, and announce the topic of your talk. This way, viewers won’t have to guess who you are and what you’re talking about.
Okay, what can I say to whet your interest?
Give the audience a reason to listen to you carefully: address the emotions of the audience, create intrigue so that people in the audience empathize with what you say.
Tell a compelling story that has obvious contradiction or conflict. The viewers will definitely want to know what happened next: “In 2016, when I was a student at the Faculty of Journalism at Moscow State University and with great enthusiasm lounged around with fellow students, something happened that changed my life forever. Once…”. With such a beginning, it is easy to do without the classic compliments to the respected audience and routine statements about the importance of the topic.
It is good practice to show the benefits of your speech to the audience. Briefly tell us what effect awaits the audience at the end: what they will learn, what they will learn and how it will be useful to them in life.
