Meetings generally are not complicated once you get used to the timing lights in the back and the different roles members of the group play. Since the average club is expected to have 20 or more members, you need a lot of roles for people to play in order to involve everyone. And, since meeting assignments vary from meeting to meeting, everyone gets practice doing everything over the course of several meetings. You are no different. Even if you think you're really good at speaking, there will come times when your heart stops and your palms sweat and you freeze before an audience.
Toastmasters can help with that.
Almost everyone will remember how wretched they felt when they gave their first speech. You may be startled to find out how supportive a Toastmasters club really can be. People who think they're really good sometimes come into Toastmasters and find out how unstructured and sloppy they really are. Even if you ARE good, you can always get better. Toastmasters can give you a lot of skills and keep good speakers improving.
