I think that is why tradtional martial arts try to teach humility from white belt on up. Because as soon as people become black belt, or have set of skills and are recognized for them in their art, then they start comparing themselves to others. Maybe this is natural, this competition, and is a survival instinct. As black belts we should realize that we hardly, know everything. The bubble is burst when black belt is achieved and he/she finds out they are really now beginning serious training. We question everything to sort through all the information and try to get an understanding. But we forget everyone has an opinion some more based on experience or fact and its hard to know if it is correct. So we learned something one way, should we immediately disregard another's opinion? No, go back to the first lessons of humility you learned as a child. The ability to say, I'm sorry. Treat others like you want to be treated. Rudeness just produces more of the same. Be open and be respectful of others, because your opinion could be the wrong one. Its hard to learn something one way, and find out it could be wrong. We are all here on this board to learn from each other. And from the complexity of this world, its easy to lose patience with others. But no matter what opinion you have of yourself, if you are rude or impatient, hurtful, or boasting, nobody wants to know you. You might be an island unto yourself. TW
