Proud of you man. I did a Toastmasters thing at work once long ago. It was hard for me. I had an easier time at a Public Speaking class I took prior to that, but that was with students who were 18-20 and I was already 28, so it was easy to be “ooh, older guy!” and use my “older guy” privilege, which allowed me to flub more and yet be respected for it more.
To your experience, that’s awesome and whether or not you join, you had an awesome experience. People “in real life” are often far more ‘real’ with each other than what you find online and that you’re stepping out and taking the steps to be able to speak out and be a physical presence and an audible voice is awesome.
