I enjoy watching the National Geographic channel. Seeing its programs made me realize how little I really know of the world.
In the learning of martial arts the more you see the wider your perspective. You can’t see every style under the sun but you can see enough to gain a more rounded perspective.
Without a good perspective it’s easy to fall under the spell of our chosen style. More so if the style was run like a cult and students brainwashed into believing in the style’s invincibility.
In this sense don’t be too quick to label another style or school as useless without first understanding your own weaknesses. Otherwise, you might receive a nasty shock one of these days when you underestimate the wrong opponent.
Thus, the more you know the lesser the probability of you falling prey to techniques that should not work so easily on you in the first place.
