....I admire the shihan like Endo or Kuribayashi, who go around throwing everyone just to give them the correct feel. Maybe 1 in 20 of the people they are throwing will get it; the rest will go on muscling the technique and insisting on their old habits. But I admire a shihan who will make the effort despite knowing it is mostly wasted....
Ya know, I feel like I'm one of these, all too often. But I also believe, and have experienced, that learning can be equally a non-linear phenomenon. It doesn't proceed one brick at a time, but as a tipping point where things suddenly come together. All that tussle is not for nothing.
