I like your post and hate it at the same time.
By the time they get to black belt and have been at it for more than a few months at most, shouldn’t they realize that rank is and should be a side effect of working hard rather than a reason to work hard? A black belt isn’t a kyu rank anymore. When does the difference in mentality change? Should someone with the experience commensurate with 1st dan really need mini tests to prove that training is worth it? Shouldn’t they realize by that point it’s about the journey and the process and not the destination and color of fabric around their waist?
I chased rank during my first stint in karate. Looking back, I had black belt on a pedestal and thought I’d be some sort of badass once I had it; I thought I’d be a part of some inner circle club of sorts. I went to my first black belt class all proud of myself. About 5 minutes after warmups, I realized I was still JR. I still got beat up the same way the seniors always beat me up. I was still better than the people I was better than before the promotion, and still not as good as the people that were better than me before the promotion. I was like the dog who finally caught the car he’s been chasing all those years. You know, that whole “now what the hell am I supposed to do with it?” look. I stopped chasing rank and started chasing improvement. Genuine improvement.
I guess it’s my long-winded way of saying a black belt shouldn’t need a carrot dangling on a string in front of them to keep them going.
