“Though you have probably never heard of [[Wally Jay]], he is considered one of the greatest judo instructors of all time. Despite never once competing in judo (only in jiujitsu), Jay consistently produced champions in judo and other martial arts. “One of Jay’s key insights was that **not everyone learned like he did**: “The biggest mistake is for an instructor to teach exactly the way he was taught. Once a teacher said to me, ‘All of my boys fight like me.’ Then when we got on the mat, not one of his students could beat one of mine. Not one. So I told him that he had to individualize his instruction.” “Jay’s realization—**what works for some people won’t necessarily work for others—is as true in judo as it is in investing**.” --- **Tags** -- [[quotes]], [[teachers]], [[expertise]], [[innovation]], **Source** -- [[20250201125729 - B - Just Keep Buying]]
