Then my opinion would be based upon what value and weight is placed on that external validation.
My opinion though shouldn't really affect anyone else, but I can still voice it.
I like my tkd belts, and as I've said I have no problems with saying so. I can progress physically without them (as in my kickboxing classes), but they're required to move through the syllabus, which I decided is something I want to do.
I know full well I could collect belts without much improvement though, so I don't weigh the belt itself as the only indicator of any improvement I make.
