For me training in the martial arts is a study. I always tell people that I study Aikido never that I do it. I feel that anyone who is serious about martial arts, or wants to look for the true essence of Ju jitsu or any marital art should think about training in this way.
Never accept what your teacher tells you as gospel. By all means listen, but think about it your self, study each technique. Think about angles , intention of Uke and Bunkai (real life application) Always try to improve your technique!
As a wise man once said. "water which does not flow stagnates"
Your techniques should always by moving on and evolving.
