Whenever I need to speak publicly, even if in front of people I know and are comfortable around, my anxiety and heart rate are up. This is something that has happened since I was a kid and although I aware of it, I tend to say the word um when I'm nervous. Earlier this week, I removed the word “um” during a presentation I did at work, and it made a noticeable difference. I felt more confident and I did not walk away second guessing how I sounded, which is something I do often when talking in front of an audience. It was a small change but definitely had a positive impact on how I felt during and after the meeting.
