Hi Mark...I'm not sure one *does* do "his" aikido. You gotta put in the work, and do **your own**.
I was thinking more along the lines of doing aikido that resembled Ueshiba Morihei's as compared to the other aikido's. Hmm ... in other words, how does one know that one is following along Ueshiba Morihei's aikido rather than Ueshiba Kisshomaru's aikido?
Hope to see you soon,
