The only limitations are the ones we put on ourselves don’t let it hold you back when I was your age my stutter incredibly bad I let it control my life. Public speaking is hard for everyone. But I’ll tell you what the amount of confidence that you will get from it will be unbelievable. Just look at. King George VI His stutter was incredibly bad. But did that stop him? No and he had to address the entire nation millions upon millions of people. My advice would be start small and work your way up. Speak in front of a small group and then slowly increased the size.
