“The giants of the race have been men of concentration, who have struck sledge-hammer blows in one place until they have accomplished their purpose. The successful men of today are men of one overmastering idea, one unwavering aim, men of single and intense purpose.”
―Orison Swett Marden
While this sounds vaguely racist, it also sounds a lot like a recipe for doing Wing Chun well, from the nuts and bolts mechanics of chain punching to the best way to achieve your martial goals.
I’ve come across this idea again and again in many different contexts and have found it to be the best way to accomplish goals.
You have to pick something to be your number one thing and pour all of your effort on it.
Just as in a fight, you have to find your way to the target, avoiding or stripping away obstacles, and then when you find the target, you pour your attack through that hole and concentrate your firepower on the one point.
