Speakers often waste their opening by repeating their name and thanking the audience, which signals a boring talk. Instead, start with a hook: a provocative question, a startling statement, or a powerful quote that captures attention and creates curiosity.
I have seen this mistake made by speakers over and over again. You see, the stage is set, your name is called, and the moment you step onto the stage, you start blabbering. Hi, thank you for having me. My name is so-and-so. I am so excited. The weather is amazing. Your audience instantly feels that you are going to be a boring speaker. They already know your name. They already had an introduction. You don't need to repeat that. What you might want to do is start with a hook. A hook like a question, a hook like a startling statement, a hook like a powerful quote. When you start with a powerful hook, your audience mentally feels relieved that this speaker is on to something and I need to pay attention.
