I thought toastmasters was great. But all the different clubs had different personalities. So, you have to find the right club. I was in it in the early 1990s and do not know how it’s evolved. What I liked about it was it had a ten speech structure and you could move on w life afterwards. Speaking in a contest beyond the club level could have you in front of 60 or more people. But something magical happens and your comfort level increases. I think there are other non toastmasters opportunities in volunteering but it’s nice to get the framework before you are thrust in front of large groups. But back to resources, I e seen some serious professional negotiation programs at my public library that really impressed me. Finally… and I’m spitballing here, I guess you could beat yourself up with speed dating events. lol.
