Admittedly, I've struggled to find a reliable way to help people reduce their public speaking anxiety, despite years of trying. I’ve advised people to do just about anything I could think of that might help, e.g., breathing, meditation. While I haven't found the thing that works every time for every person, there is one technique that seems to be more effective than most.
Even if you've already found something that works well for you, this technique is worth trying out.
