Anybody ever been to one of these? Are they useful in extracting your full potential as a speaker and building up your self-confidence? Or, are they just waffle-shops for big egos? Would I be better taking a specific course in public-speaking?
You ask some great questions and I'll do my best to (briefly) do justice to them:
1. Extracting your full potential as a speaker: that depends on the context in which you wish to speak or do speak currently. If you are intending to be an "orator" and your goal is standing ovations and applause, especially from other speakers, then TM may be useful in pulling out that potential. But if you wish to be producing results such as sales in speaking or seminars, my opinion is TM would be barking up the wrong tree, so to speak. To become a better presenter for business meetings and such... maybe.
2. Building up self-confidence: frankly, I would say that this is likely the *best* reason to join TM - is if you're a timid beginner who needs hand-holding and a lot of support because you're scared to death of speaking and not sure what to do or how to start.
3. Big egos, TM group is composed of individuals, and likely at some point somewhere, egos will be there, but it's impossible to say if you'd encounter them there for sure, or not. Each group is different.
4. Are you better off with a specific public speaking course: this is, IMO, the BIG question you pose - and the biggest problem that you face. You could, in theory, waste a lot of time - and realistically speaking, potentially a lot of money too - on clubs, associations, and/or trainings that don't help you get where you want to go or to be able to do what you want to do as a speaker. I know, I've been there. I've hung around the groups I figured *must* know how to get where I wanted to go, and realized only much later I was wasting my time and everyone was really just a wanna-be or someone who had some success but really had zero ability to help me to get to the next level. So, my best suggestion is to be very, very, very clear about what you want to be able to do and/or accomplish as a speaker - to the point of making a list that you can then compare to a training or use as a list of questions in checking out clubs or groups or classes. I really can't emphasize this part enough, and you can feel free to email me or PM me if you'd like more input.
Finally,there are a lot of decent free resources floating around on the internet but again, if you just keep sight of exactly what you're after, then you won't get sucked into spending time or money on groups or trainings that will never really help you much.
Hope that helps!
Best,
