Nothing to argue about there. I look at the three things I mentioned as darn good preparation for life stuff (martial arts, job, social, whatever) - akin to some undergraduate prep. Whereas the deeper study portion of the aiki, that in itself becomes a lifelong pursuit of self-cultivation that then feeds back in to any other activity you undertake - into graduate and beyond post-doctoral studies.
Hmm....there are things that a couple of those items will bring out...in certain people. There is a charisma, or pull
that some people seem to have. I could get into some weird ideas I have about presence and spirit and "being on" and projecting, that are easily morphed into discussions of "Ki", but that is not going to go anywhere but down hill. Funny how some of the greats had some similar observations though.
