I also get anxious thinking about public speaking... childhood stutter. The stutter is gone but the fear is still there. But when I started working full-time, I had to communicate with team members & clients. I had no choice but to move out of the comfort zone... & this has helped me a lot. I gained confidence slowly and now I have meetings, presentations and knowledge sharing sessions almost daily. It takes courage to move out of your comfort zone. Here’s wishing you success in everything you do. Good luck.
