Schools work that way, anyway. Some turn out bright pupils, some don't. Some teachers are awful, some are genuises. Problem with the TMS was, you never could "graduate"!
It helped me in public speaking and honed my ability to respond unfazed at questions thrown at random. Have not failed one job interview; and if I wanted to, I could spin a yarn.
OK, maybe I have some natural abilities that I could have developed without the TMS. But the TMS was a good thing to have.
