[ Debate ]
When I was in high school, back in the late 1980s in Calgary, Canada, there was a debate team. Or, I’m pretty sure there was. I wasn’t on it, and (regrettably) had no interest in being on it. (However, I did take a typing class, and I am forever grateful for that, because touch typing without looking is just excellent).
I regret not being exposed to formalised debating, because that is a skill so worth having. The ability to develop a coherent position based on a structure like “what, why, when, who” is central to communication. That’s the next excellence.
