I went through Toastmasters and a follow-on program called Speakwell back when I was ten and eleven years old as part of a really good youth organization that existed in Denver from 1916 to 1977 (it's also the organization where I learned to play trumpet, wilderness survival, military drill and ceremonies, small-group leadership, tumbling (to a tiny degree), and rifle marksmanship). I was too young at the time to really appreciate what we were learning, but the skills did stick and they have served me very well over the decades.I am a member of Toastmasters for over 18 years.
One of the tips we give members:
Writing a speech is like preparing to go on an airplane trip. When you're packing your suitcase, you will find that you cannot close it and it's way over the luggage weight limit. You need to remove half the stuff.
Same with writing a speech. Write the speech. The eliminate half what you have written. Be concise and precise.
There is a "Speakwell" program today, but it is not the same as it was started in the 2010's. I had thought, at the time, that Speakwell was essentially Toastmasters II, but in the years since have come to strongly suspect that they were two independent programs. I also didn't realize at the time that Toastmasters was anything other than a semester long program that was required within that youth organization as I had never heard the term prior to that, although I imagine the relationship was presented in the first meeting. It was a number of years later that I discovered that our program was actually sponsored by the local Toastmasters club and was very much the same format that they used, tailored only slightly for our age group in terms of the topics that were used for discussion and speeches. In particular, it wasn't expected that we would do much in the way of quality research into our topics. I remember my first speech, which was about the U.S.S. Arizona, and how most of my "research" came from the side of the box that the model I was building at the time came in! But, I had still had to build that out into a several minute speech, which was probably the main utility I got from that first one. I don't remember any of the specific topics of speeches after that, but I remember spending time at the public library reading up on them to prepare my speeches. That was when I first discovered Encyclopedia Britannica and the wonders of a library's card catalog. It's also where I learned the joy of just wondering through the shelves and perusing books that just happen to catch my eye.
