That’s what I mean, I believe people like the OP tend to be concerned about daily life, random encounters, completely unstructured situations. Just not sure how much public speaking carries over.
I think it’s quite possible to become a great public speaker, singer, actor or similar, and still be shy in every day life. It seems like largely separate skillsets to me. But I’m no expert.

It's not a panacea, but it's easy to get started, accessible and designed to help you be more comfortable talking.
Try it, if you want to talk to people more.
