Good points Keith. One of my main focuses is showing how the principles (not techniques) of boxing and aikido are the same. I agree though, the methodology has to change along with a certain mindset. Basically people have to be willing to do the work; the hard physical work. We have to get out of theorizing and work from an honest standpoint.
In the (self serving) video below, the kid I'm working with will do that combination or variation uncountable times. Constantly polishing his mirror so to speak. I just don't see a lot of aikido people who work at that level of consistency.
