Think about what you want to accomplish. I am the first to admit that I do not do the most impressive techniques in clinics. I do juji gatame - a straight arm bar. I do it several different ways. I teach a few ways to knock people down and go into an arm bar. I am not flashy. I'm a brawler.
All those things people say about me are true.
I watched Mike Swain do a clinic once - he was the world judo champion in 1987 - first American man to win the title. He said beforehand he was embarrassed I showed up because he was going to just teach basic techniques like o soto gari (outside leg sweep) and tai otoshi (body drop throw). On the contrary, I was impressed.
What Mike did, and what I try to do, in teaching both judo and statistics is to focus on what the students need to know, not on what makes me look good.
Too often, as black belts we are trying to impress the other black belts, as elite competitors, trying to impress the other elite athletes.
I don't teach to the top and tell everyone else to reach. That's stupid. How can I expect people to "figure out" in a two hour clinic or class what it took me months or years to figure out on my own? I teach to the middle, maybe a little below. In statistics classes, I tell people to feel free to check their text messages if I am going too slow for them.
In judo (and statistics sometimes), I tell them to help their partner or feel free to go off to the side and work on something else if you already have this down. Or, better yet, do the same technique but try to do it faster. A theme I have been harping on for years is that people know matwork but not well enough to do it fast enough to pull off in a competition.
When I teach, I start at the level most students are and work up slowly. Yes, it does mean I go over the same things a lot. That's another part of the Lego theory.
If you ever built anything with Legos you would know that the trick to having a stable structure that doesn't fall over isn't building as high as you can as fast as you can. It's in building a broad base.
So ... my point is, when I leave a class, I don't want everyone to be saying,
"Gee, that Dr. De Mars is brilliantly awesome."
I want them to be saying about one or two little things,
"Yes, I see how to do that now. I completely understand that."
