We have. Positive healthy minded seniors and teachers will help shape a positive and healthy view of the greater Taekwondo world. Negative confused minded seniors and teachers will do the opposite, dragging their follower back into the abyss of ignorance.
I don't know if their seniors or teachers were negative and confused minded so much as the students and juniors simply took it the wrong way and dragged themselves down the abyss of ignorance. I say that because often times you see students change instructors and they always end up with the same results - a mouth full of bitterness and resentment. Some people cannot learn or progress no matter who their teachers are, with their issues, prejudices or internal conflicts serving as a barrier to learning, and to freedom. The essence of what you and I try to do is to give people what they need so that they can be free, like us. Nobody tells us what to do. We do things because we choose to, because we can. But some people do not wish to be free. Instead they wish to be angry, and hang on to that anger as if that is the only thing that sustains them. Maybe they are right, maybe anger is the only thing keeping them going, anger at their parents, their teachers, their seniors.
oh well, what can you do.
