Its kind of funny to me that after I achieved Shodan many people (including other karate students) ask me "whats next?" Like thats the end of the road or something. I guess it is for some people. I do know of students who after they got their black belts considered their goal accomplished and quit karate. It makes you wonder why they even began taking it to begin with. It seems like an awful lot of wasted time to go through all that just to quit.
