If you need to introduce yourself, be creative and deliver an unexpected introduction.
For example, instead of just listing your professional credentials, use your introduction as an opportunity to be funny. Self-depreciating humor is effective when trying to persuade people, and also effective when trying to connect with an audience. In addition, self-depreciating humor is typically a safe type of humor because the odds of offending someone in the audience are slim. You are poking fun at yourself after all, not anyone else. Be careful though, you don’t want to damage your credibility or come across as unsure of yourself.
