People are all the same in ways, and they make the same mistakes all over the world, that is true of all things. In the fighting realm, a lot of people will quit at the outset, because they did not realize that learning to fight involves work. They think that if they show up, they will just absorb the vibes or something. Then they find out that it is strenuous and painful in many ways. Then, as time goes by, something dawns on them, if they ever need to use it in defense, they might get seriously hurt. Or, conversely, they may have to hurt someone else. A lot of people do not think things through, especially martial arts, which is a mystery to most folks. So when they join, and begin it is a real shock to them, that it takes serious effort. And they won't do it, so they quit. Martial Arts is not for everyone, and it takes a certain fighting attitude to keep going in it.
