You guys know I wouldn't subject you to a 56 minute video unless it was truly extraordinary and worth every second. The following video definitely is. This is an interview with Josh Waitzkin, World Champion chess master, World Champion tai chi competitor, BJJ practitioner, and all-around with-it dude. Everything that he says in this interview about tai chi and most of the things he says about chess, you can mentally re-word in your mind to be about judo or aikido and you will have had the best aikido/judo lesson you've had in a while.
If you can watch this guy's 56 minute video and not want to buy his book (from my Amazon link below) then I suspect that you weren't thinking about what you were listening to.
