Humility to be humble is part of who we are, after all line five of Dojo Kun says that we should never forget the true meaning of humility. Yet for many, lets say senior grades, who should understand a little about being humble, this is slowly being forgotten.
I have read on various social media pages that this person or that has reached his black belt and now he wants to get his next grade and how much he or she is training etc. Surely this is not part of our culture, to boast or brag about oneself or ones own goals. You should motivate yourself and those around you, but we should always show some humility.
