In a Live Seminar on Tape, He's making an analogy between being black belt with GTD and karate.

"When they jump you in a dark alley, it's too late to train."

and...

"With speed comes power that's why petite people can break boards, it's the crack at the end of the whip. Speed comes with relaxation and relaxation doesn't mean flaccid it means power... now you can tell me if this applies to anything other then a karate punch."

LOL, I thought maybe he was talking about sex here.
