Maturity is not just a matter of how old one is, or even how good one gets in the arts. One may not be mature mentally simply because he or she has aged in calendar years. Maturing in the martial arts takes patience, time and training . Just knowing techniques does not automatically qualify anyone for anything, certainly not rank. The Idea is to be totally ready before testing. It takes more than just knowing forms, self-defense and other moves to be qualified for rank.
It also takes more than threats, bravado and internet bragging.
FTD - we do not care what your race is, gender is, political affiliation is, sexual leanings, religious practices are. What is bothering many here is that chip that appears to be on your shoulder, and the seeming need you have to validate your time in. The challenges also aren't helping you any.
You are getting flak because some of these individuals have been actively training for longer than you have been breathing.
Your own words have proven that you have missed an essential part of the true spirit of martial arts training.
Spend some time in meditation, and then reread your words here and decide if that is truely the way you wish to present yourself. In fact, many others should as well.
Mastery comes with experience. Wisdom comes from experience. All things come from experience. Experience comes from time. Once can not be experienced in their youth. As was said, a 10year old black belt is rather laughable, but then again so is the fixation on belts, ranks and trophies. I once knew a man who taught a Chinese art. His students would call him "master". His usual responce was "I am but a student like you, only farther along on the journey. If you must call me something, 'teacher' will do. Please do not call me 'master', for it will be many decades before I will have earned it".
I too have trained for many years, however I am but a humble student. I have had many teachers. My master however walks in a place I am not yet ready to follow. Until then, I train, I teach and I share.
